How we grade them
| 1.6GPAMailwarmWeak | 2.0GPAWarmforgeFair | |
|---|---|---|
| Value for money | D$69 a month for 1 mailbox on annual billing, about four times the $17.99 middle for deliverability tools. Growth is $159 for 3 and Scale $479 for 10, and the page says the expert help is why. | B$10 per mailbox slot a month, billed quarterly, is at the bottom edge of what this category charges. It is per mailbox though: one pays $30 a quarter, five pay $150. |
| Free plan and trial | FNo free plan and no trial. The pricing page says it starts as soon as you connect an inbox. | DNo free plan and no trial. The only free thing is 1 placement test a month once you sign up, and warming a mailbox needs a paid slot. |
| Features | CReal-inbox warmup, provider choice, controls and placement insights. A warmup tool covers its one job, and interactions beyond the allowance cost $0.02 each. | CAutomated warmup, health checks of DNS, MX and blacklists, and placement tests. The tests are priced separately, and with too few slots it warms only from the top of your list and disables the rest. |
| Ease of use | CNo store rating on record. You connect each mailbox or SMTP account and set its controls. | CA web app where you connect each mailbox and set up warmup. No rating on record, and the listing shows mailboxes to connect and DNS to check. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
