Which one is for you
Pick Mail-Tester if

- Works for developers who want the score inside their own tool
Look elsewhere if
- Tight if you test more than 3 times a day on free, with results kept for 7 days
- Skip it if you want ongoing monitoring, since it tests one message at a time
- Watch out: the score comes from SpamAssassin and other spam filters differ
- Watch out: prices exclude VAT

- Works for agencies warming dozens of mailboxes, at $12.80 each from 51 billed yearly
Look elsewhere if
- Not for you if you want to try it before paying, as there's no free plan or trial
- Pricey if your team sends from lots of addresses, as each one needs its own warm-up
- Skip it if you need list cleaning, or DMARC managed rather than checked
- Tight if a campaign is due soon, as MailReach advises 14 days of warm-up first and keeping it running between sends
- Pricey if you pay monthly, at $25 a mailbox against $20 billed yearly
How we grade them
| 2.8GPAMail-TesterGood | 1.8GPAMailReachWeak | |
|---|---|---|
| Value for money | BSubscriptions start at $10 a month for 50 tests, level with the $10 cheaper quarter of deliverability tools. A 10-test pack is $5, and prices exclude VAT. | CAll-In-One is $20 a mailbox a month billed yearly ($25 monthly), with 20 spam tests a month included, falling to $12.80 from 51 mailboxes. Among its listed warm-up rivals Warmup Inbox costs less at $15; Warmy starts at $49 and InboxAlly at $149. |
| Free plan and trial | B3 tests in any 24 hours with no account, results kept for 7 days. One person checking now and then can live on that. | FNothing free: no free plan and no trial on the pricing page. The free spam test is a one-off checker, and the autumn sale's 20% off your first 30 days is a discount, not a trial. |
| Features | CA spam score, a configuration report and a JSON API. It uses a stock SpamAssassin setup, so a perfect score does not guarantee inbox placement, and it does one message at a time. It does that job fully, and it is a smaller job. | CIt does warm-up fully: an AI warming schedule of up to 100 emails a day, placement tests by provider, blacklist and SPF, DKIM and DMARC checks, and Slack alerts. That's a smaller job, though: no list cleaning, and DMARC is checked, not managed. |
| Ease of use | BNo store rating on record. You send a mail to a displayed address and read the result, so there is nothing to set up. | CNo App Store rating on record. You connect each mailbox, and MailReach advises at least 14 days of warm-up before a campaign, then keeping it running between them. |
| Platforms and integrations | BWeb only, with a JSON API, an iframe and white-labeling. No desktop or phone app. | BWeb, with Google Workspace, Outlook, Zoho, SendGrid, Mailgun, Amazon SES, Brevo or any SMTP provider, plus Slack and webhook alerts and APIs. No phone or desktop app. |

Worth knowing
Mail-Tester
- Scores come from a stock SpamAssassin setup; the FAQ says other spam filters differ, so a perfect score does not guarantee inbox placement.
- The free version allows 3 tests in 24 hours and keeps results for 7 days; an account with your own prefix keeps them 30 days.
- Prices exclude VAT.
- It tests one message at a time and does not monitor sending over time.
MailReach
- No free plan or free trial is listed; the free spam test is a one-off tool, not a plan.
- The vendor advises at least 14 days of warm-up before sending campaigns, and keeping it running between them.
- Each sending address under a domain needs its own warm-up, so costs grow with every mailbox.

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.
