Sender review

Free automation, which the rest of this category charges for

Sender is a straightforward email marketing tool from Vilnius that competes almost entirely on the size of its free plan. Where most platforms give you 250 or 500 subscribers to get started, Sender gives you 2,500 and 15,000 monthly emails, and it does not strip out automation to make the paid tier look better.

The builder is a conventional drag-and-drop editor. It is not the prettiest one you will use, but it does the job, and the templates are usable without redesigning them.

The three list owners Sender fits best

• Small ecommerce shops and creators with a list under 2,500 who want to spend nothing
• People who need a welcome sequence running on day one without paying for it
• Anyone who wants popups and landing pages in the same tool instead of bolting on a second subscription

What 15,000 free emails cover, and what Standard's price adds

As of July 2026: 2,500 subscribers, up to 15,000 emails per month, one user seat. Includes newsletters, automation, landing pages, signup forms, and popups. Sender branding appears on your emails.

Do the arithmetic before committing: 15,000 emails across 2,500 subscribers is six sends per subscriber per month. That is comfortable for a weekly newsletter. If you run daily emails, you will hit the ceiling in the first fortnight.

Where Sender feels a generation behind, plus the seat limit

• The email editor feels a generation behind MailerLite's, and template design options are limited
• Free is single-seat, so no team collaboration
• Paid pricing is not shown as a flat number, you have to enter your subscriber count to see it, which makes budgeting harder than it should be
• Reporting is basic, and A/B testing is not a headline feature
• Brand recognition is low, so integration lists and third-party tutorials are thinner than for MailerLite or Brevo

Worth the plainer editor if you are paying nothing

If your list is under 2,500 people, Sender is the cheapest way to run real email marketing, automation included, at zero cost. We would pick it over the better-known names for exactly that reason. The trade is polish: the editor and reporting are functional rather than good, and you will notice it if you have used MailerLite.
