## Mailspring Reviews
  ### 1. Really Not Good - so many problems

**Rating:** 0.0/5.0 stars

**Reviewed by:** Eowyn D. | Designer, Small-Business (50 or fewer emp.)

**Reviewed Date:** December 16, 2022

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

The design interface is very nice, and it's easy to set up.

**What do you dislike about Mailspring?**

Mailspring has huge syncing problems. I think 70% of the time 1 or more of my three inboxes won't sync, and the outbox has such a bad delay that emails often don't go out for a few days. What has finally catalysted me to give up on Mailspring is that an email sat in my outbox for 10 days (unbenknowst to me!) and then sent emails cancelling a standing appointment just in time to cancel the next one instead of the one I needed cancelling. Not good. 0 / 10 do not recommend.

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

It's created more problems for me than solving any of them.

  ### 2. Mailspring starts off well, but quickly goes into syncing problems

**Rating:** 0.5/5.0 stars

**Reviewed by:** Riana R. | Senior Software Developer, Small-Business (50 or fewer emp.)

**Reviewed Date:** August 16, 2022

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

Easy to set up with a modern look and feel

**What do you dislike about Mailspring?**

Although it starts off well, it quickly runs into syncing problems.
It almost looks as if it was only tested on gmail accounts. 
Using any other imap server only works for a short time, then all of a sudden starts showing only the last 4 or 5 emails or reports that it can't sync.
Although re-validating the account settings reports no errors, mailspring is unable to re-connect and sync all emails

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

None - just creates more errors than it solves

  ### 3. Pretty, but lacking key functionality

**Rating:** 1.0/5.0 stars

**Reviewed by:** Verified User in Computer Hardware | Small-Business (50 or fewer emp.)

**Reviewed Date:** October 12, 2021

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

Pretty, easy to configure.  Nice interface

**What do you dislike about Mailspring?**

No filtering, hard to select multiple emails to perform an action on.

**Recommendations to others considering Mailspring:**

Look at something else

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

Dissatifaction with other email clients. This isn't really any better though, in some ways is worse.
