Sender

The most generous free plan we found

2,500 free subscribers, 15,000 free emails a month, and automation included at no cost. Almost nobody offers all three.

Who it suits, and who it doesn't

Worth your time if

  • You want a working welcome sequence without paying anything yet.
  • Your list is at or under 2,500 and you want to start free.
  • You publish a newsletter as well as running a course.

Look elsewhere if

  • A smaller name with a smaller integration list. Check it connects to your course platform before you commit.
  • You want a bigger free allowance. Kit gives 10,000.

The details that decide it

The things that bite six months in, read off Sender's own pages. Where we could not read a page reliably, the row is left out rather than guessed at.

Moving your list in
Done-for-you migration is free, but only on an annual plan with 20,000 or more subscribers. Below that you import it yourself. Source
Deliverability
Claims deliverability "up to 99%". Their own figure, on their own features page. Source
What else it costs
No transaction fee on sales, and no charge for unsubscribed contacts. Each subscriber tier carries its own monthly send cap. Source
Getting your list back out
The friendliest exit terms of the nine. Cancelling drops you to the free plan instead of deleting anything: their help page says subscribers, campaigns, automations, forms and reports are all retained. Source

Sender, answered

Does Sender have a free plan?
Yes. Sender's free plan covers 2,500 subscribers and 15,000 emails/mo. We read this off their pricing page on 5 September 2026.
Can Sender send an automated welcome sequence on the free plan?
Yes. Email automation is listed on the free plan. That matters more than it sounds: most free plans let you broadcast but will not automate, so a new subscriber gets nothing until you sit down and write to them.
What does Sender cost once the free plan runs out?
The entry paid plan is Standard at $7/mo, up to 1,000 subscribers. Prices on every platform here move with list size, so treat that as the floor rather than the bill.
What is the catch with Sender?
A smaller name with a smaller integration list. Check it connects to your course platform before you commit.
