MailerSend is a fantastic service for tech teams looking to streamline email communication within their applications through a seamless API. The level of service provided by their support team is truly remarkable - they are incredibly prompt and responsive.

That's the last straw: I had a list from our restaurant with 9800 emails from clients and everything worked fine for years but what I experience lately with SMTPServer is a scandal.. After Covid etc we got a a lot unsubcribes and stayed with 5000. I cleaned this list with a software I had and stayed with 3400 emails. I gave this list with 3400 to MailerSend to be cleaned again by them, I don't remember the price, and started sending the emails. Result: a) I was kicked out because of to may bounces. b) I discovered at the same time that the has showed on their Anaytics page as delivered but have not been delivered at all. c) In my analytics page my account shows to be 'active' but i can not send any emails, after sending it says on the SMTPServer page 'delivered', but none of the emails arrive. From 50.000 emails I have bought I have sent 11.000 cleaned emails and I am altready kicked out for having to may bounces. I got finally al letter from a collaborator names 'Cesar' telling me: It seems that your domain name is already associated with an account that was already paused and suspended because of a high bounce rate. We never received a response so your account was suspended and we won't be able to provide you with our services anymore. No reply to my following messages no explanations. Would they send the money back - hmmmm, I doubt. Easy job for to make quick money: B Rgds Manfred

Stay away from mailersend at all costs. Mailersend is a 'HASSLE-FOCUSED' company. They use their terms of service to manipulate customers into using their platform but when their platform sends 100% of your test emails to spam (or missing) and you know you've configured your DNS properly and have a reputable domain to send from, they don't care about that or when you request a refund for really bad service and results. It's a scam with empoyees forced to flaunt that it's a great place to work all over their website (what other companies do that??) when the leadership team is probably dysfunctional and isolated. If you don't believe me sign up to their platform and send test emails using a reputable warm up platform. (not using glock apps because companies like mailersend know how to get good scores using that app) You'll see that all or almost all of your emails from the warm up process are going to spam or missing. THAT'S A MAJOR RED FLAG. People who have given mailersend rave reviews have clearly not really tested the platform. That probably explains why mailersend is one of the few platforms that cannot deliver what they claim they can. I would recommend a 'terms of internal practice' review for mailersend and maybe even dump Ignas. It might be time for a major shakeup. UPDATED: After reading mailersend's response I thought it would be prudent to respond. I ran two seperate warm up tests and both of them came back with 24 emails going to spam and 6 missing out of 30 total for each run. I ran the tests over 2 days so clearly there couldn't have been a temporary glitch in their system and the domain used for the sending email address was reputable meaning no blacklists and it's old enough to not be considered new by ESPs. The DNS records were also entered correctly. I think mailersend responded politely to what is probably an alarming exposure internally and they have no real solution in place to address it. How could any platform survive when 67% respondents give 5 stars and 33% give 1 star. That means 1 out of 3 people are giving mailersend 1 star. Clearly not good. You either love it or really hate it. I would stick with other SMTP providers who have a reputation for delivering results and taking care of their customers. I'm an engineer and data driven. The results of my findings are 100% accurate and again, mailersend knows how to get good results from glock apps, which is why sites like emailtooltester give inaccurate results from their test data because they're also using glock apps for their data results.

Hi Kenneth, we're quiet concern regarding your feedback. We believe and trust in our product and wonder whether this may have been a temporary issue we were experiencing during the time your review came out. However, it's hard for us to figure this out without any data. We would really love to understand where you're coming from, if you'd love to email us and share with us more of what happened, we'd be more than happy to dive further into this and rectify if needed. https://www.mailersend.com/contact-us

Terrible customer service. Account blocked and when asked for clarification on why I was repeatedly ignored. Lost money and time and MailerSend will simply not respond because in my experience they simply do not care.

Scam- They are letting intruders register services on my domain. I think Google will stop it before it goes too far, but this is NOT enough security for a mailing service anyone would actually want to use.

I had upgraded my account for the amount of $30 (50k plan) and i had sended only 500emails and my account has been immediately suspended by them.I had checked with the support and they had told that they will not be able to activate my account.When i asked for the refund they had told they will not be able to provide the refund.I am really very disappointed with the service.So better dont use this platform they will scam you.
