| Free plan and trial | C | A free spam test is offered on the home page, but its monthly limit is not stated. |

That makes this kind of software worth paying for, not this one in particular: 39 of the 61 other email verification and deliverability tools grade higher. It costs $276 a year.
What you could not
- Reading the reports inbox providers send about your domain.
- AI features, unless you pay a model provider for each request yourself.
