The questions we get most.
Do you store the email I forward?
The test mailbox auto-deletes after the report finishes. We never store the raw email body beyond what the report references — subject line, header metadata, and the classification result. EU-hosted in Bratislava, GDPR by default. See the privacy page for the full details.
How is this different from GlockApps / MailReach?
Those tools focus on inbox-placement warm-ups (the deliverability-obsessive workflow) and bill per seed list per month. We do one thing — you forward one email, we tell you in plain English where it'll land and what to fix. Pay-as-you-go credits or a light €9.99/mo plan instead of a heavy seat-based subscription, EU-hosted instead of US, and a voice that sounds like the platform you already use (Beehiiv, Kit, Substack) instead of a deliverability vendor.
When does billing start?
Only when you buy credits or start the €9.99/mo plan. Forwarding an email and reading the score is genuinely free — no card collected, no trial countdown, no automatic upgrade. The only thing you ever pay for is the AI deep-dive.
How do I cancel?
Same screen you upgrade on, one click. We don't make you email us, talk to a chatbot, or wait for end-of-cycle. Your remaining month stays active; we don't re-bill.
What do I actually pay for?
Forwarding an email and getting the score, plain-English verdict, inbox placement and the SPF/DKIM/DMARC server checks is free and unlimited — across Gmail, Outlook and Yahoo, all in one report. The paid unit is the AI deep-dive: the full AI breakdown with rewrites, which costs 100 credits (one unlock). A €4.99 pack is about 5 deep-dives, or €9.99/mo is about 11 a month.
What's the refund policy?
30-day money-back, no questions asked. If your first paid month doesn't help you ship a better send, email hello@mailtester.ai and we refund the charge.
