Welcome
What it is, who it suits, its grades and the ten things to know first

GPA, above 18 of the 81 other cold outreach tools we grade

The report card
Best for email warm-up billed per account
MailToaster warms up email accounts through a peer network, billed per connected account. It does that one job, costs $26 an account a month on yearly billing, and the pricing page and home page give different trial lengths.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $26 an account a month billed yearly, $29 monthly, charged for every mailbox you warm. Ten mailboxes cost about $260 a month. |
| Free plan and trial | C | A free trial with no card, but the pricing page says 7 days and the home page says 14. |
| Features | D | Warm-up, DNS checks and progress reports. It does nothing else, so you need sending tools elsewhere. |
| Ease of use | C | No store rating on record. You connect each mailbox and pick a warm-up profile. |
| Platforms and integrations | C | Web only, for Gmail, Google Workspace and Outlook. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who MailToaster is for
- Fits if you have a few mailboxes that need warming up
- Works alongside a sequencer you already pay for
Who it is not for
- Pricey if you run many mailboxes, because the fee is charged on every connected account
- Not for you if you want sequencing or leads, as it only warms up
- Watch out: the pricing page says a 7-day trial and the home page 14 days
- Skip it if you want a clear commitment, since the yearly rate carries a minimum commitment the page does not spell out
Good to know
Good for
- Senders who already have a sequencer and only need warm-up
- Teams warming several Google Workspace or Outlook mailboxes
- Users who want to pay by account and cancel any time
Worth knowing
- Pricing is per connected email account, so cost grows with every mailbox.
- The pricing page and homepage state different trial lengths, 7 and 14 days.
- The yearly rate is 10% below monthly, with a minimum commitment the page does not spell out.
- It only warms up mailboxes; there is no sequencing or lead tool.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace MailToaster you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 53 of the 81 other cold outreach tools grade higher. It costs $312 a year.
What you could not
- A network of real inboxes that open and answer your emails.
- Reading the reports inbox providers send about your domain.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. MailToaster’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
