**Reviewed Date:** May 23, 2024

**What do you like best about OutboundSMTP?**

The most helpful feature is when I have purchased this subscription and I want to send the outbound message instantly. And as they have the tagline, which says "10 minutes to deploy garuntee," which is very easy while implementing the SPF and DNS for the verification and starting to send the messages. And I have been using this tool from last 6 months.

The thing from which I got a bit disappointed with the customer support team, as they are a bit slow for providing the solution of our problem.
