Nothing troubling to share (no passwords, etc needed). Immediate results. I also like the free trial use for spot checks. **What do you dislike about Mailtester.com?** As with most such systems, it's short on expert advice to address problems when it finds them. Yes, there are names of issues, but a consistent database of answers with actionable steps would be great. **What problems is Mailtester.com solving and how is that benefiting you?** Sometimes we have complaints about deliverability to and from our domain. This is a way to make sure it's not a configuration problem. ### 2. mailtester review **Rating:** 5.0/5.0 stars **Reviewed by:** Vinay B. | DevOps Engineer, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal gift card as thank you for completing this review. **Source: G2 invite:** Invitation from G2.

If we send mail incorrectly, the ISO will mark it as spam, and our mail reputation will drop. **What do you dislike about Mailtester.com?** In the mail tester, everything is fine, but they could start rolling out an open-source version with fewer features so we can better integrate it into our environment. **Recommendations to others considering Mailtester.com:** I would recommend it **What problems is Mailtester.com solving and how is that benefiting you?** We are solving the problem that our mail costs less and that our mail reputation does not get hit and does not go into spam, as was happening earlier, which we have saved. ### 4.

Without this, I don't like anything else about Mailtester anymore. It definitely used to be great. **What do you dislike about Mailtester.com?** I added Mailtester to G2, yeah, kind of just to let you guys know that it's the worst and don't ever try it! I used to like it when it was free. The verification rate was good, service was fast. I even suggested that they get a paid service for people like me who can verify lots of emails at once. Then after a few years, they make it totally paid, no free version, just 10 free credits! Okay, that was good for me cause, unlike the free version I could now verify all my emails at once within minutes. But gosh, they got bad so quick. I had their monthly subscription of 5000 emails/day for $79. And, there would be at least 5 days every month when I couldn't verify a single email, because the process showed 0% for hours after hours. **Recommendations to others considering Mailtester.com:** Never ever use it! it's just not usable anymore. Unless you just want to check some emails for normal things, not run an email campaign or something. **What problems is Mailtester.com solving and how is that benefiting you?** Was using it to verify my emails, I verify at least about 50K emails every month. So, it was a vital thing for me. But I had to switch to others (I switched to Bouncer and Hunter.io). ### 8.
