Quickness and deliverability Mailersend is one of the best mass mail send in the current time. We are on the developing stage, and we put on competition almost 10 mass mail ESP, where we need test and to be sure that our transactional mails don't end up into our clients Spam box, or "Promotions" tab for google.. Mailersend was the winner, the second a client register into our system instantaneously the mail is in our clients Inbox (a lots of ESP endup into Promotion tab when it comes to google). I would recommand Mailersend for any one who wants a reliable, sure solution for mass mail sending. Also Mailsersend has one of the bets free plan offer in the market, over 12.000 mail/month, it is a must for a business to automate their mail sending machinery to send/try/experiment with that amount of mails/month after that upgrade to a paid plan (I would say most ESP average is 3000 mail/months which is not that much for tests).

Great experience with the platform Great experience with the platform. Very good service that offers a wide range of features and functionalities. The platform is easy to use and the user interface is intuitive, and the whole process of setting up and sending emails is seamless. One of the standout aspects of the platform is its exceptional support. The customer service team is highly responsive and knowledgeable. They go above and beyond to assist with any questions or issues that arise, ensuring a smooth and enjoyable experience.

Not recommended First I wanted to connect Google Firebase to import authenticated users to mailersend. But the extension doesn't do anything, contacts still need to be imported manually. After trying to import contacts manually, mailersend tells me to upgrade because I cannot import users without credits. After upgrading, mailersend tells me that the subscription doesn't do anything for new contacts, but I need to buy credits to import them für 250$. After requesting mailersend to refund my money, they told me that they never refund money.

Impressive support people I am just testing the suitability of mailer send, but great software is only as good as the support. I ran into a question and given I am currently only on a free account I was amazed to get a response within half an hour which allowed me to continue working. And it was from a human being !!!
