## Sendio Reviews
  ### 1. Review of Sendio

**Rating:** 4.0/5.0 stars

**Reviewed by:** Jack O. | Lead Software Engineer, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 15, 2021

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

Seems very solid at stopping spam and phishing using safe sender lists and other low level security checks on incoming email. Very easy to set up and maintain.

**What do you dislike about Sendio?**

The Sender Address Verification reply email seems like it might be cumbersome to an email sender or the sender might be confused by it, but our users can accept messages on behalf of the senders in case they do not verify themselves.

**What problems is Sendio solving and how is that benefiting you?**

Much less spam and lowered risk of phishing. We have had users fall for phishing so this makes it worth it.
