Plans

The Free plan at $0/mo covers 500 emails/month, which is where an agent would start.

Can an agent buy this on its own?

A price is only half the question. The other half is whether software can get from landing on the site to making a paid call without a person, which is what the AgentReady measures under adopt.

For Mailersend, it can create an account itself; no sales call stands in the way.

Against that, the signup flow assumes a human at a browser; credentials must be minted by hand in a dashboard. Each of those is a point where an unattended run stops and waits for a human.

That works out to 70/100 on adopt, against 47/100 overall.
