"Great service at a very reasonable cost"
What do you like best about Folderly?

Folderly helped us improve our email deliverability with a series of simple yet very effective configuration recommendations. Additionally, their email engine helped warm up our email address against an extensive collection of mail servers. Combining that with speedy and friendly responsiveness led to a very smooth and enjoyable project.

What do you dislike about Folderly?

There wasn't anything to dislike. We are new to the nuances of email deliverability, but their hand-holding throughout the process gave us the confidence that everything will work out fine.

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

We noticed that many of our outbound emails were going into spam boxes and wanted to find a way to fix that.

"Must-have tool for cold outreach campaigns"
What do you like best about Folderly?

We need to send significant volumes of emails in our business, and not all of them are replied back. That's why our mailboxes are the red flag for the spam filters. Folderly helps us keep our emails always delivered and placed in the Inbox of our recipients. If there're any possible reasons for the decrease in deliverability, we get a notice and stop some campaigns for a short period until it's fixed. Overall, I see a dramatic increase in our business metrics since getting started with Folderly.

What do you dislike about Folderly?

I don't have any idea; my team enjoys working with Folderly.

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

Having our cold outreach emails sent to the Inbox folder of the recipients; increasing the performance of outbound email campaigns.

"5/5 software that fixes deliverability for multiple mailboxes"
What do you like best about Folderly?

I am really satisfied with our deliverability results. First of all, we could use Folderly for multiple mailboxes. That facilitates the process, since you can track your results for all the mailboxes on the same dashboard. There was a deep dive into tech details, such as ESP’s and domain setting, DMARC records, sender reputation etc. Some of these are set once and then there’s no need to modify them. After that, there is a routine, such as warming up the mailboxes and spam checking. So I can recommend Folderly as an additional, but necessary tool to have your emails sent to the Inbox.

What do you dislike about Folderly?

I would prefer a video explanation for the set up process, there are some specific steps that took us time.

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

We are aware that our emails reach the inbox folder. After several claims of our customers who never received our emails, we have started to look for a solution. So now in the dashboard, we can track our deliverability results.

"Folderly solved all our email deliverability problems!"
What do you like best about Folderly?

The functionality and user experience is excellent. It's also very easy to use and helps the user to optimize the platform for their unique needs. They really found a specialized niche helping to drive the "anti-spam" initiatives that so many of us marketing and sales leaders have. Thank you Folderly!

What do you dislike about Folderly?

There is nothing I can think of at this time. But this is really something you should look into. Have them give you a short trial and give it a whirl!

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

Email deliverability is a common problem with outbound marketing and has plagued the industry since the advent of spam filters. Folderly uses AI, thousands of data points and a proprietary SAAS platform to ensure that emails are always delivered on time and never get caught in the purgatory that is spam filters. They actually coined the phrase, "The Anti-Spam Thing" and have stayed true to their word.

"Very user friendly, great support, and delivers results instantly!"

Folderly was easy to implement and help ensure that our emails were being delivered to inboxes and avoid spam/junk folders. With more security around viruses and hacking, we noticed less email engagament and higher spam blocking. Folderly helped our email not only arrive in inboxes but our open rates improved as well! They also have amazing support - very responsive and helpful!

What do you dislike about Folderly?

Nothing! User friendly and it works - what more could you ask for!

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

Email delivery issues, drops in engagement and open rates. Folderly helped ensure our emails weren't being filtered to spam and were being received. They also helped to improve our open and engagement rates overall.

"Appointment setting and lead generation"
What do you like best about Folderly?

Email outreach has never been made easier. We can spin up emails and domains then easily start emailing all of our prospects with a click. We know our emails are being sent to our prospects with the highest reply and open rate yet. More emails in-front of our prospects eyes means more meetings booked and deals closed. Huge increase in sales since we have started using this platform and we don't know how we got by without it! The Folderly team is extremely responsive and on-top of everything. I recommend this for anyone looking to increase sales and generate more revenue.

What do you dislike about Folderly?

I don't have anything negative to say about Folderly.

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

Quick turnaround time. More emails delivered, higher response rate - more meetings booked and deals closed.
