Kit vs MailerLite vs AWeber

Overview

Kit vs MailerLite vs AWeber is not a simple lowest-price contest. AWeber Plus is the best operational fit for an agency that must keep several client lists in one account. MailerLite Power is the stronger retainer-friendly choice when the agency needs unlimited team seats and sending for one shared audience. Kit Free wins for an agency's own publication, because it reaches 10,000 subscribers at $0, but its published Free plan has only one user.

The three tools charge for the same job in different ways. Kit makes subscriber capacity the headline and attaches user allowances to each plan. MailerLite prices by active subscribers and sending volume, then uses seat and send ceilings to separate Free, Comfort and Power. AWeber publishes subscriber tiers with a defined monthly send multiplier, while Plus removes the practical user and list-profile constraint.

That distinction matters more than a feature checklist. A marketing agency charging clients a monthly retainer may want a known platform bill that can be absorbed into delivery. A production team running several separate client lists may value list separation and unlimited logins more than a low entry price. An agency that owns one newsletter may rationally stay on a free plan for years. This guide prices those three jobs at 1,000 subscribers and again at 10,000, then explains where each plan stops being useful.

Kit, MailerLite and AWeber are approved affiliate partners with live tracking links in the site registry. That relationship does not change the dated figures or the trade-offs.

How we chose

The fixed comparison point is 1,000 subscribers because it is large enough to expose the difference between a genuine free allowance and a paid tier, while still appearing on each vendor's public pricing material. The growth checkpoint is 10,000 subscribers. At that size, Kit Free is still inside its published ceiling, AWeber shows separate Lite and Plus tiers, and MailerLite's page still describes the send multiplier and unlimited-send Power plan even though its fetched dynamic price fields do not expose the dollar amount.

Every price and plan limit stated here was read from an official vendor page on 6 November 2026. Kit's page displayed Creator and Pro in the annual view for 1,000 subscribers. MailerLite's page displayed starting prices and plan rules but not the selected 1,000 or 10,000 subscriber dollar amounts in the fetched content, including when the page was fetched with subscriber query parameters. AWeber's page published the full Lite and Plus table, including monthly and annual totals.

The comparison keeps billing labels intact. An annual total is not silently divided into a new quote, and a promotional first-year display is not presented as a standing renewal price. The pages also use different meanings for a send. MailerLite says one send is one email to one subscriber. AWeber states a monthly multiplier for the selected tier. Kit says there are no sending limits on any plan. These are not interchangeable promises.

The agency test has four questions. First, is the bill driven by subscribers, sends, seats or some combination? Second, can the account support the people who need to work in it? Third, can the team keep client audiences separate without promising an unpublished sub-account model? Fourth, what changes when the list grows? The email marketing software hidden fees guide is useful for the costs that sit beside the headline subscription.

Kit for agencies

Best for one owned audience Kit Free $0 up to 10,000 subscribers, read 6 November 2026

Kit suits an agency that runs its own newsletter, lead magnet or paid publication. Its strongest commercial feature is the Free ceiling: up to 10,000 subscribers for $0 per month. The plan includes unlimited landing pages and forms, unlimited email broadcasts, audience tagging and segmentation, and digital-product and subscription selling, all read from Kit's pricing page on 6 November 2026.

That is a different proposition from “free for a small team”. Kit's current comparison publishes 1 user on Free, 2 users on Creator and unlimited users on Pro. An agency can therefore keep a substantial owned list at no subscription cost, but it should not describe Free as a shared production workspace. If one account lead owns approvals, list hygiene and sends, the limit may be acceptable. If an account manager, copywriter and client need routine access, the user rule becomes the real upgrade trigger.

Free also turns off several agency conveniences. The page lists no visual automation builder, no automated email sequences, no RSS campaigns, no Kit MCP, no 100-plus direct apps and no branding removal on Free. Kit says there are no sending limits on any plan, so the free limit is not a monthly send quota. The limit is audience capacity, access and the features needed to run a repeatable client workflow.

At the fixed 1,000-subscriber checkpoint, the page displays Creator at $33 per month and $390 billed yearly. It displays Pro at $66 per month, $593 billed the first year, and a limited-time $50 per month promotional figure. The page labels the annual view as saving 17% and says the Pro promotion applies only to the first year before renewal at the standard rate. These are separate displays, not three interchangeable monthly prices.

Best paid Kit choice for a small team Kit Pro Unlimited users and reporting, with the 1,000-subscriber annual display read 6 November 2026

Creator is the sensible paid step when a two-person team needs unlimited visual automations, unlimited sequences, Kit MCP, polls, integrations, RSS campaigns, branding removal and support. Pro is the team-access step because it adds unlimited users, engagement analytics, deliverability reporting, collaborative editing and the insights dashboard. The page does not publish a complete paid dollar table for 2,500, 5,000 or 10,000 subscribers in the fetched content. Kit Free remains $0 up to 10,000, but that does not provide a paid-price forecast.

Consider a two-person agency with one owned 1,000-subscriber newsletter. Kit Free costs $0 and may cover the broadcasts, forms, landing pages, tagging and segmentation, but the current published Free allowance is one user. Creator is the named paid route at $33 per month in the annual display, or $390 billed yearly. A five-person agency at the same list size cannot treat Creator as an unlimited-seat plan. Pro is the published unlimited-user route, with the $66 annual display and the separate $593 first-year promotion recorded rather than merged.

Kit does not publish a client-sub-account allowance in the pricing page reviewed on 6 November 2026. Unlimited Pro users describe access to one account, not separate client-owned workspaces, separate billing or automatic offboarding. That makes Kit a better choice for one list that the agency owns than for a pooled operating layer holding several client audiences. The Kit review covers the same user and annual-display distinction in more detail.

MailerLite for agencies

Best for a retainer-funded shared team MailerLite Power Unlimited seats and monthly emails, read 6 November 2026

MailerLite is the most explicit about charging for usage rather than feature access. Its pricing page says paid pricing is based on the number of active subscribers and sending volume. Comfort and Power then publish different capacity limits for seats, automations, sites, forms, products and monthly sends.

Free costs $0 per month for up to 250 subscribers, with 2,500 monthly emails and 2 user seats, read 6 November 2026. It includes campaigns, free automations, a free landing page, free signup forms, a free digital product or booking, MCP access and 100-plus integrations. The current comparison also shows 3 active automations, 5 automation steps, 1 website and 1 landing page, 3 active forms, limited newsletter templates and limited subject-line generation.

Comfort starts at $12 per month, and Power starts at $25 per month, read 6 November 2026. Comfort publishes 3 seats, 50 automations, 10 forms, 10 sites, 5 digital products or bookings, and 10 times the ceiling of the selected subscriber tier in monthly emails. Power publishes unlimited seats, unlimited automations, unlimited forms, unlimited sites, unlimited digital products and unlimited monthly emails subject to fair use.

The fetched official page did not expose the exact Comfort or Power dollar amount for the selected 1,000 or 10,000 subscriber tiers. That remained true when the page was fetched with ?subscribers=1000 and ?subscribers=10000. The correct comparison is therefore not a guessed MailerLite quote. At an up-to-1,000 tier, Comfort's stated 10-times rule gives 10,000 monthly emails. At an up-to-10,000 tier, the same rule gives 100,000 monthly emails. Power is unlimited subject to fair use at both checkpoints.

Best for a team beyond three editors MailerLite Power Unlimited seats solve the access cap, not separate client ownership

A two-person studio with 1,000 subscribers can fit inside Free on seats only if it stays below 250 subscribers, so the list checkpoint requires a paid tier. Comfort offers three seats and a 10-times send allowance. Power becomes the known answer when four or more people need access, when unlimited monthly email is important, or when the automation and site ceilings become a shared resource. The exact tier dollar amount must be read from the live selector before purchase.

At 10,000 subscribers, MailerLite's plan logic is clearer than its fetched price field. Comfort's stated 10-times rule means 100,000 monthly emails and the plan still publishes 3 seats, 50 automations, 10 sites and 10 forms. Power still publishes unlimited seats and monthly emails subject to fair use. MailerLite's active-subscriber rule also matters: an address that was active at any point during a billing cycle can count until the billing anniversary, even if it is later deleted.

AWeber for agencies

Best for several separate client lists AWeber Plus Unlimited users, email lists and automations, read 6 November 2026

AWeber uses the clearest subscriber-tier table of the three. It publishes Lite and Plus rows with monthly cost, annual cost and monthly sends at each audience size. It does not price the subscription by the number of staff logins. Instead, user, list and automation allowances are attached to the plan.

AWeber Free is a separate no-time-limit offer. The official Free page read on 6 November 2026 says it covers up to 500 subscribers and 3,000 emails per month, with one landing page and one automation. It requires no credit card, and Free sends carry AWeber branding. The current Free page does not publish a user or list-profile count in the fetched content, so those numbers are not assumed here. The separate 14-day paid-plan trial is not the same as the no-time-limit Free plan.

Lite is the economical one-list route. It publishes 3 users, 1 email list, 3 landing pages, 3 email automations and 1 custom segment. Sending is 10 times the selected subscriber tier each month. At 1,000 subscribers, Lite costs $25.00 monthly or $250.00 annually and includes 10,000 monthly sends. At 10,000 subscribers, it costs $100.00 monthly or $1,000.00 annually and includes 100,000 monthly sends, all read from AWeber's pricing page on 6 November 2026.

Plus is the agency plan when several audiences have to live in one account. It publishes unlimited users, unlimited email lists, unlimited landing pages, unlimited email automations and unlimited custom segments. Sending is 12 times the selected subscriber tier each month. At 1,000 subscribers, Plus costs $45.00 monthly or $450.00 annually and includes 12,000 monthly sends. At 10,000 subscribers, it costs $135.00 monthly or $1,350.00 annually and includes 120,000 monthly sends.

AWeber Plus is not automatically a reseller system. Unlimited email lists are a plan allowance, not proof of separate client billing, client-owned logins or isolated sub-accounts. The agency still needs an operating agreement covering data ownership, approvals, authentication and offboarding. The AWeber review for small agencies explains those limits without treating list profiles as a full client portal.

Kit vs MailerLite vs AWeber pricing compared

Caption: official plan figures and limits read on 6 November 2026. “Not published” means the fetched vendor page did not expose a number, not that the cost is zero.

The table shows why the three-way answer cannot be reduced to one “cheapest” column. Kit Free is $0 at both checkpoints, but the published user allowance is one. AWeber provides the most complete dollar comparison at both checkpoints, with Lite and Plus rows. MailerLite provides the most useful team-capacity distinction, with 3 seats on Comfort and unlimited seats on Power, but the fetched page does not publish the dynamic tier dollar fields.

For one list owned by the agency, Kit Free is the strongest cost answer up to 10,000 subscribers. The trade-off is the one-user rule and the missing Free automation features. MailerLite Free is more collaborative at 2 seats, but its 250-subscriber ceiling is far lower. AWeber Free reaches 500 subscribers and 3,000 monthly sends, but its no-time-limit offer is much narrower than Kit's broadcast and form allowance.

The seat, send and billing traps

A free subscriber ceiling is not a free agency workspace. Kit's 10,000-subscriber ceiling can look unbeatable until a second person needs access. MailerLite's 2 Free seats are more collaborative, but 250 subscribers and 2,500 monthly emails can end the experiment quickly. AWeber's Free offer has 500 subscribers and 3,000 monthly emails, while its current Free page does not publish a user count in the fetched text. The plan names must stay attached to their access rules.

Sending allowances change the fixed-list result. Kit says no sending limit applies on any plan. MailerLite Comfort uses 10 times the top of the selected subscriber tier, so an up-to-1,000 tier carries 10,000 monthly emails and an up-to-10,000 tier carries 100,000. Power is unlimited subject to fair use. AWeber Lite uses 10 times the selected tier and Plus uses 12 times. One weekly campaign is not the only send to count. Automations, resends and separate client messages use the same allowance where the plan defines one.

AWeber's annual display is an annual commitment. Lite's 1,000-subscriber row is $25.00 monthly or $250.00 annually. Plus is $45.00 monthly or $450.00 annually. The annual amount is not a newly calculated monthly quote. It is the published cash total for annual billing. The same distinction applies to Kit's $390 Creator display and its $593 first-year Pro promotion.

MailerLite's missing dynamic price is itself a buying issue. The current fetched page says Comfort starts at $12 and Power starts at $25, then exposes a selector that should vary with subscribers. The returned page content does not include the exact 1,000 or 10,000 dollar values, even when fetched with subscriber query parameters. An agency can use the published send and seat rules, but it should obtain the current selector price before putting MailerLite into a client quote.

Automatic movement between tiers affects forecast risk. Kit says it automatically upgrades to the next subscriber tier when a plan limit is exceeded. MailerLite says paid accounts automatically increase the subscriber limit and charge the next tier when active subscribers exceed the current limit. Free sending locks above 250 active subscribers. AWeber publishes tiered prices and send capacity, so the agency should monitor the selected row rather than assuming a lower tier remains in place after growth.

Separate lists are not automatically separate clients. AWeber Plus publishes unlimited email lists, which makes it the best documented choice for several audiences in one account. Kit Pro publishes unlimited users, and MailerLite Power publishes unlimited audiences and seats, but the pages checked do not state separate client billing or isolated client workspaces for either. If the contract needs client logins and offboarding, verify the account model before migration.

Who should not buy this

Do not buy a paid plan simply because the agency has a client. If the agency owns one newsletter and one person handles the workflow, Kit Free may be enough up to 10,000 subscribers. MailerLite Free may be enough for a small pilot under 250 subscribers and 2,500 monthly emails. AWeber Free may be enough for one small audience under 500 subscribers and 3,000 monthly emails. The correct free choice depends on the audience and workflow, not just the $0 label.

Do not use a 1,000-subscriber price as a 10,000-subscriber forecast. Kit does not publish the larger paid rows in the fetched page. MailerLite's exact selected dollar fields were not present in the fetched page. AWeber does publish its 10,000 rows, so its figures can be used for a dated scenario. Where the number is absent, the honest action is to confirm it before signing or to choose a platform whose published table supports the proposal.

Do not promise separate client sub-accounts because a plan says unlimited users, audiences or lists. A team can still need separate data ownership, permissions, billing, export and deletion rules. The no-contract email marketing software guide and MailerLite vs Kit for agencies cover related commercial and exit questions.

Our verdict

Choose AWeber Plus for several separate client lists. At 1,000 subscribers it is $45.00 monthly or $450.00 annually, and at 10,000 it is $135.00 monthly or $1,350.00 annually. Both rows publish unlimited users, email lists and automations, plus 12 times the selected subscriber tier in monthly sends. That is the clearest documented fit when list separation and shared access matter more than the lowest entry price.

Choose MailerLite Power for a retainer-funded team when unlimited seats and sending are the real requirement. The official page publishes a $25 starting price, unlimited seats and unlimited monthly emails subject to fair use, but its fetched dynamic fields did not publish the exact 1,000 or 10,000 subscriber dollar amounts on 6 November 2026. Get that current selector amount before passing the platform cost into a retainer. Power solves the team and send ceilings, but the public page does not establish separate client sub-accounts.

Choose Kit Free for one list the agency owns. It is $0 up to 10,000 subscribers with unlimited forms, landing pages and broadcasts, and no sending limit published on the page. The price advantage ends as an agency access decision when a second person needs routine entry, because Free publishes 1 user. Creator publishes 2 users at the 1,000-subscriber annual display, while Pro is the published unlimited-user route.

AWeber Lite is the useful middle choice for one client list and up to three users. MailerLite Free is the useful small pilot when 250 subscribers and 2,500 monthly emails are enough. The practical decision is therefore conditional: AWeber Plus for several lists, MailerLite Power for a retainer-funded shared team after confirming the live tier price, and Kit Free for one owned audience.
