MailReach: cost, fit and limits
MailReach is an email warmup and spam-testing service made by the French company The Brain Company SAS that builds mailbox reputation through automated, human-like activity and reports where messages land. It is aimed at outbound sales and marketing teams that send from Gmail, Outlook or SMTP mailboxes.
What to know first
MailReach combines a warmer, a spam tester and a reputation dashboard under a per-mailbox price. Pay-as-you-go spam test credits are billed on their own, and higher tiers add automatic tests with Slack and webhook alerts. The price examples on the page changed across the toggles we read, so total cost is the thing to confirm in writing. The only AI feature it names is a smart warming algorithm.

Who MailReach is best for
Teams that want warmup and testing together
The all-in-one plan bundles the warmer with at least 20 spam test credits, so one purchase covers both building reputation and checking where messages land.
Outreach on non-Google mailboxes
MailReach says it works with any provider that supports SMTP, and lists Zoho, Brevo, Mailjet, Mailgun, SendGrid, Amazon SES, Sparkpost, Ionos and OVH beside Gmail and Outlook.
Operators who use AI assistants
A policy page describes an assistant connection that exposes mailbox status, reputation score and warming settings, and says passwords and tokens are excluded from what an assistant sees.

What MailReach does
- Smart warming algorithm
- Warmup is described as automated and organic, using human-like activity rather than canned replies. The page names no further AI detail, so the algorithm cannot be assessed beyond the claim.
- Inbox placement by provider
- Spam tests report where a message lands at each provider, and each credit covers one test with a deliverability report. Higher tiers rotate the seed list so repeated tests do not hit the same addresses.
- Authentication and blacklist checks
- The dashboard checks blacklists, SPF, DKIM and DMARC, plus reverse DNS on higher tiers, which gives a first place to look when a mailbox starts to underperform.
- Alerts to Slack and webhooks
- Automatic spam tests can notify a Slack channel or a webhook, so a team learns about a placement drop in its own tools without opening the dashboard.
- Assistant connection
- MailReach's policy page describes data an AI assistant can read, including address, status, reputation score and inbox and spam statistics, with request logs kept for 12 months.
How MailReach handles your data
MailReach's terms name the operator as The Brain Company SAS, registered in Paris, France, under French law. Its policy page says that when an AI assistant is connected, MailReach does not use the data it receives from the assistant to train AI models, keeps assistant request logs for 12 months, and never exposes mailbox passwords or tokens. It also uses the first and last names of connected mailboxes to personalize warmup emails. Hosting location and message content access were not stated on the pages we read, and no security certification was listed. The vendor's policy was not checked for those points.
Where MailReach falls short in practice
- Totals are hard to read. The pricing page showed example monthly totals that moved with the toggles, including one figure of $1,323 for 80 mailboxes and 200 test credits. Get a written quote before committing to a larger mailbox count.
- Warmup caps at 100 a day. Warmup plans list up to 100 emails per day per mailbox. Teams that want the higher daily volumes some competitors publish should compare that limit before choosing.
- Nothing here sends campaigns. MailReach prepares and tests mailboxes but does not run sequences. A sales team still needs a separate sender, which adds a second subscription and a second place to manage mailbox connections.

MailReach: common questions
What does a MailReach spam test credit cover?
One credit buys a single inbox placement test with a deliverability report, according to the pricing page. The warmer plan includes at least 20 credits, and Pay As You Go credits are billed separately. The page does not say how credits expire, so ask before buying a large pack.
Is MailReach a European company?
MailReach's terms of use name The Brain Company, a simplified joint stock company registered in the Paris trade register at an address in the 8th arrondissement, with the contract governed by French law. The pages we read did not state where servers are hosted, so confirm that separately.
Which mailbox providers does MailReach work with?
The pricing page says MailReach works with any email service provider that supports SMTP, and names Gmail, Outlook, Zoho, Brevo, Mailjet, Mailgun, SendGrid, Amazon SES, Sparkpost, Ionos and OVH. Check any specialized provider with support before connecting it. Support can confirm anything unusual.
Does MailReach train AI on my data?
Its policy page says it does not use data received from AI assistants to train AI models. That statement concerns the assistant connection. It does not address the warmup pipeline or message content, so the vendor's policy was not checked for those points on the pages we read.
What does MailReach check besides placement?
The dashboard tracks reputation and checks domain and inbox health, including blacklists, SPF, DKIM and DMARC. Higher tiers add a spam words checker and reverse DNS checks. Those cover authentication and content problems, but not list quality or complaint rates.
