Transactional Email Service for our Hosting Clients
We use SMTP2GO to provide transactional email service for all the sites we host. Simple setup with sub-accounts allows us to tailor usage on a per-client basis. Excellent support as well. Submit a ticket and be working with a real person within minutes.

We started with the free service
We started with the free service, but outgrew it and now are using the paid subscription. Everything has been working well and we have not missed any alerts!

Very pleased with the service
We've been using SMTP2GO for a few years now. The service has been great for us. Easy to configure, and very little down time. When there is an issue, it's not hard to track it down in the logs. Very pleased with the service.

Good customer service
Had an excellent experience with customer service, just for that they get a good review. Will change if it gets worse for any reason.

What a great experience
What a great experience. Signup and setup was easy and fast. SMTP2GO has a nice clear dashboard with all the enterprise level features you need. Support was fast and friendly. The initial review for full account activation out of sandboxing was trauma free. Mail deliverability is excellent and a real plus that tracking is deactivated by default - which builds trust for business transactional emails and privacy. Very generous free tier and the upgrades are well worth it. If you want a no-nonsense provider for bulk emails, you found it.
We really appreciate the SMTP2Go product. It provides a safe option to allow our customers to send emails from their copiers and websites or other web based apps that do not work with modern OAuth. SMTP2Go does not save the sent items in a mailbox and provides much more privacy as a result. SMTP2Go provides the ability to create verified senders that satisfy SPF, DKIM and DMARC requirements to satisfy email security requirements and allow them to be properly received.
I was having problems trying to get my file to go through and was unable to open the web sight to look at a different plan in which the file didn't get distributed until all emails were able to be sent. I sent an email to support and never heard back.

Hi Angie! We have been unable to locate any tickets from you in our system - are you able to retry contact and if possible, attach the ticket number so we can investigate what went wrong. We'd love to help out! :)

Excellent SMTP service
Excellent SMTP service. We use it for our printers for scan to email, much easier to use than Microsoft 365 and more reliable than our ISP's SMTP server.
This is a simple and intuitive way to send verified emails to Microsoft 365 without enabling SMTP on an account. It works well. We use and recommend it.

The service has been top-notch
The service has been top-notch, especially compared to others. Their biggest mishap in 2 years was the IBM datacenter fire. It was a tough lesson, but a lesson none-the-less. They did a great job with communication in the aftermath and helped folks recover their work even. I will keep on working with them.

Hi Jim,
Thank you for taking the time to leave a review.
Is it possible you have confused us with another SMTP provider? There was never a fire at one of our data centres.
Fantastic service. Very reliable and flexible for our needs.
