"Consistent help, but not 10/10 user experience"
What do you like best about Folderly?

I evaluated their warmup. It doesn't use the other users for mailing interactions, so it seems pretty secure.

What do you dislike about Folderly?

This is not an easy task to set up an account. I have no other tools to compare with, but they gave me some headaches...

What problems is Folderly solving and how is that benefiting you?

Obviously, email delivery rates. The only benefit is delivery performance.

"Sent 1750+ Warmup Emails overnight to Spoil my Domain Reputation"
What do you like best about Folderly?

I thouht Folderly was a good Email Warmup service where you can add unlimited ids to increase your Sender Reputation but I'm not sure anymore.

What do you dislike about Folderly?

Folderly sent 1750+ warmup emails overnight just to 2 email ids of their own and all of them bounced backed. It was on Friday night and I was lucky enough to catch it before weekend otherwise It would have been a disaster.

What problems is Folderly solving and how is that benefiting you?

Fodlerly was supposed to increase the Sender's Reputation by sending automatic warmup emails. Once your Sender's Reputation increases, Chances of your email landing in the Inbox increases especially if you are sending cold emails to your leads.

"Beware: Folderly destroyed our email reputation by sending 42000 undelivered emails within two days."
What do you like best about Folderly?

Using Folderly to warm up our email domain. We thought it was an easy to setup solution.

What do you dislike about Folderly?

Folderly sent 42,000 undelivered emails in 2 days (Saturday and Sunday) using 8 email addresses in our domain. Our team didn't realize the issue until Monday. Our email domain reputation is completely destroyed. That is completely the opposite of why we wanted to use Folderly. Folderly support never answered our requests to help solve the issue. We called and emailed. All we heard was "Oh, that is terrible". But, no support whatsoever. DO NOT USE this product.

What problems is Folderly solving and how is that benefiting you?

We wanted to monitor and improve email deliverability. However, due to a bug, Folderly sent 42000 undelivered emails using our domain. They completely destroyed email reputation.
