Reliable, Straightforward, and Effective: My turboSMTP Experience **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** September 30, 2025 **What do you like best about Turbosmtp?** I have been using turboSMTP (serversmtp.com) for 1 month now and overall I am very satisfied. Here’s what stands out to me: Excellent deliverability — The emails I send almost always reach the recipients without issue. I see far fewer bounces or delivery failures than with previous SMTP providers. Easy to configure — Setting it up was smooth. The onboarding process, DNS settings, and SMTP credentials were straightforward. Even if you’re not an expert, you can get it running quickly. Support for multiple sending domains — I can manage more than one domain as a sender, which is essential for me since I operate several projects and brands. Transparent interface & analytics — The dashboard gives useful stats (open rates, deliveries, etc.), so I can monitor performance. Responsive support & infrastructure — Their infrastructure seems reliable and they offer support (tickets, chat) when needed. What really makes the difference for me is their superb technical support, which gives me complete confidence and security. **What do you dislike about Turbosmtp?** The 100,000 email limit per month on the Basic plan is somewhat restrictive if your needs increase, and if you need more, you'll need to upgrade to the Professional plan, which almost triples the cost. The Basic plan only allows one custom tracking domain, which can be cumbersome if you want a complete branding approach for multiple domains or projects. **What problems is Turbosmtp solving and how is that benefiting you?** TurboSMTP helps me manage multiple sender domains while maintaining excellent email deliverability, increasing the efficiency and reliability of my communications. ### 5.

Please read **Rating:** 0.5/5.0 stars **Reviewed by:** Kenneth S. | Small-Business (50 or fewer emp.) **Reviewed Date:** September 18, 2023 **What do you like best about Turbosmtp?** Prices were reasonable but still not worth it **What do you dislike about Turbosmtp?** PLEASE READ THIS. This service is terrible!! Below are my stats. I have an extremely clean list of 9,585 email addresses. I had the list cleaned twice by different companies making sure all bad addresses were removed. The 9,585 was the final count of all valid addresses. Here are the results 9,585 sent 103 opened 79 bounced I put in 12 personal emails to verify the send. Of the 12, 1 was received, 2 went to spam and 9 disappeared. I’ve been doing this for a long time and never had such terrible results. I investigated and found out the reason for such a low open rate and because 9 of mine that never got to their destination was because this company’s smtp,s are all being rejected by Yahoo, Google, Hotmail and others. They don’t even go in spam. They are refused. On their statistics they say they were all delivered. That’s a true statement but they never put in their statistics how many were rejected. Years ago this was an extremely good service but because they let a lot of spam accounts in, their reputation was destroyed and now everything is being rejected **What problems is Turbosmtp solving and how is that benefiting you?** None.It didn't deliver what it was supposed to deliver ### 15. Easy to use and simple to setup **Rating:** 4.0/5.0 stars **Reviewed by:** Manik S. | Lead Integration Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** August 10, 2022 **What do you like best about Turbosmtp?** Great customer support. Helpline folks are very helpful and friendly. The other good thing is that its easy to setup and maintain. **What do you dislike about Turbosmtp?** Multiple connections are not allowed. It is not a good tool for bulk sending emails. We have tried sending out blast emails for emarketing and it wasn't a great success. **What problems is Turbosmtp solving and how is that benefiting you?** This is being used for bulk sending emails to send out event invites. The delivery rate is good and the emails are not landing in junk / spam folder. ### 16. Nothing of what they advertize is real **Rating:** 0.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** February 22, 2022 **What do you like best about Turbosmtp?** The only thing this company has to offer is the staff on the chat are friendly and polite. **What do you dislike about Turbosmtp?** Honestly, everything else is terrible. Line 2 support is awful. They leave tickets unanswered for weeks and months, and they may even ignore them. No one ever answers the phone number the list for tech support. We called a different times of the day, we were on hold for hours and then we got disconnected. Their dedicated IP service is a total scam. You pay for a dedicated IP, and you maintain it in good shape and high reputation, and then suddenly they take it away and assign you a different IP with a very bad reputation. and their tracking gets your IP blacklisted all the time. They never give you an answer to why they are doing this. And when we demanded that you do not do this, they re-routed our email from a different IP with a terrible reputation—fooling us. They made us think we had our IP untouched, but our email was being routed from a different IP. Again, you never respond to the ticket when we ask why they do it. Another problem, this is not a real company. This service is run by a company called Delivery Tech Corp. Their address in San Diego does not have anything except the server. The phone number they list on the Better Business Beaurue is fake. When we filed a complaint, the BBB came back and said they could not reach them. Bottom line, if you care about your online reputation, DO NOT USE this service. **What problems is Turbosmtp solving and how is that benefiting you?** We could not get any of our problems solved with them. We finally had to cancel the service and get a refund. No one even cared to ask why we cancelled. In fact, they ruined our online reputaion when they routed our email from IPs with very bad reputaion while we are paying for a dedicated IP ### 17. Turbo Marketing via Mails **Rating:** 4.0/5.0 stars **Reviewed by:** Chetan N. | Associate Consultant, Mid-Market (51-1000 emp.) **Reviewed Date:** January 21, 2022 **What do you like best about Turbosmtp?** The platform that they provide still needs core development.

It provides a trial version which helps to check the product itself and if it works you can use it. **What do you dislike about Turbosmtp?** As said above, it still needs development. Basic things are working fine, but room for improvement is available. **What problems is Turbosmtp solving and how is that benefiting you?** Still in the early stage to say if it can be classified as a platform that's solving our issues. ### 18.
