"Email infrusctructure pros"
What do you like best about Folderly?

Great software to get the email infrusctructure right.

Now the alert system notifies us about the upcoming issues, and Oleksandra helps to keep track of indicators.

What do you dislike about Folderly?

Nothing critical to mention; If there were problems, we solved them quickly.

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

Folderly helps keep all our domains and mailboxes healthy. This ensures that both marketing and sales emails always reach the recipients inbox.

I learned about Folderly from a colleague, before that I didn't even know it was possible to avoid sending marketing emails to promotions. Responsive support team delved into my case and helped me set up my email infrastructure so that I would not get to spam or promotions again. Now our open and click-through rates are twice as high.

What do you dislike about Folderly?

I would love to recieve folderly alerts as slack notifications

"Kudos for email deliverability testing"
What do you like best about Folderly?

The clarity of usage. The actual rate of email landing folders and, what's important, the tool highlights your issues within different email sending systems. Also, it helped monitor DNS and blocklists.

What do you dislike about Folderly?

Unfortunately, the tool lacks email outreach ...

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

With Folderly we are solving email delivery issues that our business has encountered. This tool gave me an understanding of the landing folders of my emails and an Inbox placement for different email sending systems. Now I know why some of my prospects didn't receive my emails.

"Workable way to increase email engagement"
What do you like best about Folderly?

The tool saves time and efforts for our email marketers. It analyzes technical settings of our domain and mailboxes, consequently prevents emails from going to spam.

What do you dislike about Folderly?

No email verification feature. It would save time and money to combine those features in one tool.

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

The primary goal is to fix delivery and open rates. At the same time to maintain domain health, and organize domain infrastructure.

"Maintaining high open rates"
What do you like best about Folderly?

Easy to use and integrate with any existing email software. We use several providers, and integration was one of the deciding points.

What do you dislike about Folderly?

For now, I can't say anything. Nothing bothers me until I see results.

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

The main benefit is the complex 'health' of our email ecosystem. Apart from Folderly solution, the customer support team shared several tips for the long-term delivery strategy. As for the tool, tests and warm-up run smoothly, and email campaigns perform extensively.
