- Watch out: annual plans can't be refunded after purchase, according to the pricing FAQ
- Watch out: the name is in flux, as Flowrite was folded into MailMaestro and its old team moved to a separate product

- Watch out: higher Pro credit tiers cost more, at prices the page doesn't list
- Watch out: there's no free plan, and the 30-day money-back guarantee isn't a trial
How we grade them
| 2.0GPAMailMaestroFair | 2.0GPAJace AIFair | |
|---|---|---|
| Value for money | CPro is $12 a seat a month on annual billing ($15 monthly), which sits near the dear end of email tools: the middle is about $8 and the cheaper quarter starts at $3. | DPlus is $20 a month billed yearly, $25 monthly, against an $8 middle for this category and a dearest tenth that starts at $25. That buys 10,000 credits, 2 inboxes and chat over 1 year of history. Custom integrations and MCPs need Pro at $40, and the higher credit tiers aren't priced on the page. |
| Free plan and trial | CFree forever with no card, but only 3 AI requests a week. That's a taste, not a plan you can work on. The Pro trial is 14 days. | CNo free plan. Plus and Pro both start with a 7-day free trial you can cancel any time, though nothing on record says whether it asks for a card. The 30-day money-back guarantee isn't a trial. |

It lives inside Outlook and Gmail, and the listing shows no standalone client. | CFull reply drafts in your style, labels like Needs Reply applied for you, plain-language rules, and Flows that watch for matching mail then make calendar events or update Notion, Slack and HubSpot. But it runs on a Gmail or Outlook account rather than being one, and every job spends credits. |
| Ease of use | CNo store rating on record. You add it to your mailbox and connect your account, then learn the templates and shortcuts. | CNo rating on record. Drafts are saved back into Gmail or Outlook, but you connect accounts, describe your own labels and rules, and keep an eye on a monthly credit allowance. |
| Platforms and integrations | CA browser and Outlook add-in for one job, with Teams, Zoom and Google Meet listed. No phone or desktop app of its own. | BA web inbox and nothing native: no iOS or Android app yet, and the docs suggest keeping the Gmail or Outlook phone app alongside it.

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.
