MailerSend, Inc.Reviews of mailersend.com

I’m currently developing a SaaS project and was looking for a transactional email service to handle user interactions. I decided to give MailerSend a try. The UI was intuitive and the setup process went smoothly. However, they asked me to complete a form detailing my project for verification purposes, which I took seriously and filled out thoroughly. Unfortunately, they came back with a firm refusal and restricted my account without providing any specific reason. I reached out to their team for clarification, but their response remained vague and unhelpful. I also took the time to carefully read their Terms of Use, and my project did not in any way violate their guidelines. Overall, it was a disappointing experience, especially since I had already integrated MailerSend into my codebase and had to rewrite everything to switch to a different provider.

If you looked up the legal definition of Fraud by False Representation, you would see MailerSend. Even the name is misleading. We wanted a cheap solution for transactional emails used internally. Clearly that was too much of an ask. They throw at you the SMTP relay credentials for you to plug into your application, & it doesn’t authenticate. Nothing works with this company. Of course, they did the standard deflection practice that all staff use when they know that their product is s*** but can’t admit it by way of stating that “we have had no other complaints”, clearly not realising they have a Trustpilot profile with a one-star rating. They then expect you to troubleshoot their product, like I have the time to do that. Unless a company is willing to pay me for my time, I will not troubleshoot another companies product. I design software myself, I would not dream of asking an end user to troubleshoot any software I design. They even replied to their review claiming it works despite the mass of one-star reviews claiming the opposite. Poor product, poor “support” staff. We closed our account within 24 hours.

they stopped processing our emails because our misspelled their account names, and wanted us to pay for another address validation service to continue processing

Terrible Ethics!! Terrible Customer Service. They will increase their price and auto charge your card and not give you a credit back. Terrible.

STAY AWAY FROM THIS COMPANY!!! It’s impossibly hard to use without any support or resources. This is waste of time and funds i have amazing skills for email management and marketing but this was the worst system ever and i wasn’t able to use it. They have horrible product and even horrible customer service which is never helpful. I canceled without being able to use their service and paid for standard plan but never got to use it. Wasted my time and nerves and there is no refunds whatsoever. If there is one company i definitely hate its this one. Save yourself and stay away! They don’t care and want to scam people into buying their shitty products .

Tried MailerSend for 1 day couldn’t even send 3 test emails to my personal accounts. Account wasn’t approved, and my API key got blocked without explanation. Double-checked their terms, broke no rules, but got zero support or clarification. If you want surprises in production, go ahead. Otherwise, avoid this service.

I’m deeply disappointed with my experience using MailerSend. Here’s what happened and why I cannot recommend their services: Unauthorized Charges: While on the Hobby Plan, I was shocked to receive an invoice for over $9,000 USD. Upon investigation, I found that an unauthorized user had upgraded my subscription without my consent. I immediately deleted the user, changed my admin password, and activated two-factor authentication (2FA) to secure my account. Recurring Compromises: Despite being the only user on the account and securing it with 2FA, the same issue happened again. It is baffling how unauthorized activity could still occur, suggesting a deeper issue with MailerSend’s platform security. Lack of Resolution: I reached out to MailerSend support, but their response has been inadequate. They failed to address how these breaches occurred or provide a satisfactory resolution. As a paying customer, I expected a prompt investigation and refund for the unauthorized charges, but this was not delivered. Platform Security Concerns: Based on my experience, I believe the issue may not be limited to my account but could indicate a broader security vulnerability within MailerSend’s system. If their platform cannot protect accounts secured with 2FA, it raises serious concerns about their overall security infrastructure. Recommendation: I cannot, in good conscience, recommend MailerSend to anyone. Their failure to secure accounts and address unauthorized activities has cost me time, money, and trust. If you’re considering using their service, I strongly urge you to look elsewhere.

I previously had an account with mailersend with no issues, then our company got acquired, so we closed the previous account and opened a new one with the new company name. We applied for approval, but it was rejected, so we applied again with more information, we were surprised that the account got suspended with the following message "We have not been able to determine that your account fully complies with our policies and community standards." Although we provided a screenshots from our previous account but still we got suspended regardless. Don't waste your time, they are clearly incompetent. You might have your account suspended in the middle of a big marketing campaign. They will just cite their bullsh!t "polices and community standards", so avoid using them at all costs.
