"The solution that really works"
What do you like best about Folderly?

Folderly boosted our email deliverability rate from 39% to 99% and eliminated critical deliverability issues! Now we regularly run spam fixes to maintain maximum email deliverability during cold email campaigns.

What do you dislike about Folderly?

We spotted no issues while using Folderly.

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

We eventually came to the conclusion that it was becoming more difficult to successfully sell by email and get messages delivered to recipients' inboxes. It became quite difficult to expand the clientele by sending out cold emails. As part of our email marketing stack, Folderly has quickly become an essential tool. Folderly helped our company improve our email deliverability rate, enhance our return on investment, and expand our client base via cold email marketing.

"Folderly is totally worth the money we pay for it"
What do you like best about Folderly?

Folderly team is very responsive and always ready to assist us with everything we need. The solution works well, and we like the "Spam triggers" feature, which allows us to spot any issues with our email campaigns and fix them at once.

What do you dislike about Folderly?

At first, we were a bit hesitant because of the price, but it's surely worth it. It's better to pay more for a stable solution than go with a cheaper competitor and not get the desired result.

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

Since we wanted to improve the results from our cold email campaigns to acquire even more customers, we found out that except for fixing our templates and building a relevant lead base, we needed a solution that would maintain our domain health and protect our mailboxes from spam filters. After a thorough research, we chose Folderly and are totally happy with this decision. Folderly guards our sender reputation, and we see the progress and the spike in new deals, because we're sure that our emails don't go to spam.

Folderly has a very intuitive and user-friendly interface. It allows me to check the situation in my account with a few clicks. The result has exceeded my expectations - we have a high Folderly score, which means that our emails are sent to the Inbox, and we can confirm this with a higher number of responses to our cold email campaigns.

What do you dislike about Folderly?

I'm waiting for the release of the "Best practices" feature.

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

Folderly fixed our DNS records and now runs spam fix campaigns on the daily basis, maintaining our high sender reputation and letting us deliver more emails to the inboxes of our potential clients.

"Folderly moved me from promotions to inbox!"
What do you like best about Folderly?

Folderly was able to help me organize my DMARC so that things ran more smoothly. They helped me to set up extra mailboxes and walked me through the process of all the tech details that I found very difficult to understand. Extremely knowledgable and easy to communicate with quickly.

One mailbox was running perfectly within weeks, while the other took almost 6 months. I'm happy with the results even if it took some time.

Folderly has helped me to land in the inboxes of clients, after having had serious deliverability problems.

"I can recommend Folderly to everyone who wants to fix the performance of their email campaigns."
What do you like best about Folderly?

By increasing our email deliverability rate, Folderly helped us increase the return on investment of our marketing efforts. It spiked up to almost 100%, giving us confidence that our emails aren't being marked as spam and allowing us to convert more leads into customers through email. Our Customer Success manager assisted us throughout the way of setting up the account and adding right DNS records. The price is totally worth the service and results!

We have nothing but positive thoughts and feelings regarding Folderly.

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

The return on investment from our cold email marketing was insufficient. Folderly assisted with the remedy by removing the deliverability obstacles that were preventing our emails from reaching the inboxes of their intended recipients.

"Folderly is the answer to all the "What's going on with my email campaigns?" question."
What do you like best about Folderly?

Folderly is a user-friendly and informative service that assists us in identifying and resolving issues that cause our emailing campaigns to underperform. We appreciate the team clarifying what we need to do to solve the situation and aiding us every step of the way.

What do you dislike about Folderly?

There's nothing we dislike about Folderly.

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

Email marketing is how we reach out to potential prospects and clients. As a result, we need good deliverability and inbox placement rates. When we first started sending significant email volumes, we saw a drop in our open rate, which continued to fall. We eventually didn't know whether our emails went to the Primary Inbox or not. After careful consideration, we signed up for Folderly and began utilizing the solution. So far, the results have been good; we know what caused the decrease, and Folderly is assisting us in correcting it by performing deliverability fix campaigns on a daily basis. That is just what we need.

"Great results from our email campaigns"
What do you like best about Folderly?

Folderly helped us get our emails out of spam folder and now helps us maintain a great deliverability rate. We're so glad we handled the task of taking care of our deliverability to the professionals, and we don't need to try to figure out what's going on in our account by ourselves - Folderly experts are always responsive to all our questions and inquiries. Now, as we see our deliverability rates spiking up to their highest numbers, we can be sure that all our emails are reaching the inboxes. It also influences the number of leads and deals we get.

What do you dislike about Folderly?

We haven't noticed any pitfalls and points we dislike about Folderly and the team.

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

We're using email channel for both acquiring new leads and communicating with our existing customers. We once noticed that a lot of our lead acquisition campaigns don't bring the desired results, and even the messages to our current clients go in vain. So, the main goal was to identify what happened to our mailboxes and resolve the issue. Folderly team helped us a lot - they immediately responded to us, showed us around and gave advice on how to make the most of the platform. As we've been using Folderly for some time, we can clearly see the results. We monitor our Folderly Score, check and eliminate spam triggers and test our templates for spam words. All these efforts combined bring us what we've been looking for - our emails stopped going to spam, and it bring us additional lead acquisition and communication opportunities.
