"Best ESP infrastructure and service"
What do you like best about SMTP.com?

Very good infrastructure with white-listing, dedicated sending IPs and in-depth reporting.

What do you dislike about SMTP.com?

We've had a few challenges on sufficient leadtime and notifications on maintenance work by SMTP.com. However, our account manager is in close contact with us to ensure this is not happening again in the future. As SMTP.com is only hosted at one provider, we've had routing issues once. It would be beneficial if SMTP.com would have a second provider in a different country/location.

What problems is SMTP.com solving and how is that benefiting you?

maintaining ESP infrastructure for different accounts with dedicated sending IPs. Centralized support with dedicated account management to easily identify and solve issues. Centralized Reporting and billing.

"Almost Always Dependable and Easy to Use"
What do you like best about SMTP.com?

What I like best about SMTP.com is that I don't have to worry about junky and spammy websites causing the shared IP address to get penalized. That was the most critical factor for me when it came to me choosing SMTP.com over a competitor.

What do you dislike about SMTP.com?

The two main dislikes I have at the moment are that SMTP.com doesn't have a more affordable plan, and it does go down for a few minutes every few months or so, which could equate to lost leads. I don't expect it to have a free version, but a plan for light use would be nice, as I don't think I will ever generate more than 1,000 emails in a month. Overall I don't think anyone can go wrong with signing up and incorporating SMTP.com into their website's tech stack.

What problems is SMTP.com solving and how is that benefiting you?

I am sending out notifications or web form submissions.
