The report card
Best for warming up cold-email mailboxes
Mailivery warms mailboxes by swapping emails with a network of other inboxes and rescuing messages from spam. Plans are set by daily warm-up volume, from $21.75 a month on yearly billing. Each mailbox is limited to 100 to 250 warm-up emails a day, and the listing's pricing cards disagree on one figure.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | $21.75 a month on yearly billing, $29 monthly. That's in the cheapest quarter ($25), though the plan only warms up and checks mailboxes. |
| Free plan and trial | D | 7-day free trial, with no card rule stated and no free plan. |
| Features | C | Warm-up, blacklist monitoring, verification credits and placement tests. It does the warm-up job, which is smaller than sending, and verification credits are one-time. |
| Ease of use | C | No store rating on record. Connect each mailbox, set volumes and watch the results. |
| Platforms and integrations | B | Web, with Gmail, Google Workspace, Microsoft 365, SendGrid and SMTP. |
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 Mailivery is for
- Fits if you already send cold email and need your mailboxes warmed
- Works for small teams with a handful of mailboxes
Who it is not for

- Tight if you have many users: seats stop at 2, 4 and 10 across the plans
- Watch out: the yearly Professional card says 600 emails a day, the table says 800
- Pricey if you want more verification credits, which are one-time purchases
Good to know
Good for

Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Mailivery 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.
It costs $261 a year.
What you could not
- A network of real inboxes that open and answer your emails.
- Checking that an address exists without writing to it.
- It plugs into other products, Gmail, Google Workspace and Microsoft 365 among them, and has an API.
