"Love email performance when using Folderly"
What do you like best about Folderly?

I see dramatic results for cold emails. We implement tones of best practices from them. Before we sent all the emails from 2 senders, we never respected the sending limits, added links, didn't have a valid signature, and BIMI. Their success team helped us to divide sending volumes on different subdomains and senders. Additionally, they set up adequate DNS records for each outreach tool we use in our practice. Permanent warmup for each mailbox that sends cold emails helps us maintain high open and reply rates.

What do you dislike about Folderly?

Nothing to dislike, but the cost is expensive

"Great software to fix and maintain email deliverability"
What do you like best about Folderly?

Their warmup is excellent; you can modify templates and check template preview, adjust volumes sent. But I never did it; the platform suggests the proper volume itself. The emails are automatically deleted and never overwhelm my mailbox. Maintenance is highly effective for solving deliverability issues.

What do you dislike about Folderly?

The onboarding process could be more straightforward, I suppose

"Intuitive and easy to use"
What do you like best about Folderly?

There are a lot of insights on my emails. Thanks to Folderly, we switched to another email service provider, added subdomains for promotional emails, fixed DNS records, and started to score way much better. At some point, we were ready to give up on cold emailing, but Folderly proves that everything depends on your approach.

What do you dislike about Folderly?

Nothing to complain about; everything is fine so far.

We maintain the high performance for cold emailing.

"Helps to keep email campaigns on track"
What do you like best about Folderly?

I use Folderly to achieve the goal performance of email campaigns. I don't visit Folderly's account often; there is no need. On a monthly basis, I sync up with the support team, and they share the results. As long as we see the excellent performance of email campaigns, I am satisfied with the tool.

What do you dislike about Folderly?

Deliverability is something I was not aware of before, and as a new user, It was challenging to add mailboxes.

"Rescue for marketing emails"
What do you like best about Folderly?

The platform helped us to rescue open and engagement rates for our marketing emails. There was a significant drop; emails went to promotions and then to spam. Folderly fixed domain and DNS set up issues, and thanks to permanent warmup, it keeps us on the top of the mailbox.

What do you dislike about Folderly?

It took time to understand how to add mailboxes.

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

It doesn't take much time but brings great results.

"Good email deliverability solution."
What do you like best about Folderly?

The platform gathers together everything about fixing spam. We have started by adding our mailboxes, checking email placement, and fixing some tech issues. The warm-up maintenance helps to have continuously high deliverability rates. The system of alarms helps to predict and fix in advance all the problems that can occur. Warmup is automated, so we don’t see any emails in the mailbox; we track the growth in open and engagement rates.

What do you dislike about Folderly?

At first, we were hesitating about the price, higher than the average on the market. However, the results in campaigns’ performance cover the cost.

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

Maintenance of high email performance. We have high delivery, open and engagement rates by fixing deliverability issues, which is primary for our business.

"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.

"Helps our company to maintain high deliverability rates."
What do you like best about Folderly?

The tool is a complex approach for spam fix and keeping deliverability on track. Folderly does a complex job of analyzing and solving every possible reason for being in spam. The customer support team is highly responsive and is ready to find every unobvious issue. The interface is intuitive and easy to use.

What do you dislike about Folderly?

The price is comparatively expensive, but it gives the declared results.

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

Deliverability rate impacts all the following metrics: delivery, open, reply rates, and then the success of all the email campaigns, so we perceive it as a necessary tool to integrate with our ESP. Email deliverability is more fragile than it seems and needs to be improved permanently. The whole email campaign could go in spam because of several spam reports.

"Deliverability and outreach experts."
What do you like best about Folderly?

It’s an automated supplementary tool for each email service provider. Spam fix is handled ‘turn-key’, starting from domain check and DNS settings to permanent warm up. The support team is very nice.

What do you dislike about Folderly?

By now on, I haven't seen any problems with it.

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

From several mailboxes our emails were going to spam due to SPF settings and poor sender score. When using Folderly, our recipients see emails in the Inbox. It saves time when spam fix is automated and increases revenues from email marketing campaigns.

"Great tool for cold outreach campaigns."
What do you like best about Folderly?

With Folderly you can see the results of all the mailboxes on the same dashboard, which is very convenient. We had our domain and DNS settings fixed, and the sender reputation improved.

What do you dislike about Folderly?

It covered everything promised. No problems.

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

In our business we send many emails from different mailboxes, so we needed a complex tool to have all the emails sent in the Inbox of our prospects. By fixing spam, we increased conversions in our outreach campaigns.

"Great tool for spam fix. Cold outreach improved."
What do you like best about Folderly?

I can mention the complex approach. They check every possible aspect that can impact low deliverability. Some issues were fixed that we had no idea about. Even working for a while with email outreach, there are some tech details neglected that make the campaigns suffer. So this software does everything ‘turn key’.

What do you dislike about Folderly?

The hardest thing was to set all the records up at the beginning.

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

Metrics of cold outreach campaigns. We send great volumes of emails, and sooner or later they are blocked in spam. Regular actions on improving sender reputation, warming up mailboxes etc bring stable and high results.

"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.

"Necessary tool for everyone who sends emails. Deliverability fixed"
What do you like best about Folderly?

About the software, I’ve enjoyed that there’s not that much you need to do, it’s automated, but you really see the metrics grow. We could track a great increase in the open and reply rates. The support team does their best. I have enjoyed working with them.

What do you dislike about Folderly?

Nothing to mention at this point, Folderly works well.

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

We had poor results of our outbound campaigns, emails were not reaching the prospects' inbox. Folderly takes care of all the spam traps. So having deliverability fixed, we had much higher results with the same internal efforts.

"Great help for email deliverability! Good value for money"
What do you like best about Folderly?

The tool is automated and it's not time-consuming. We could see great improvements in our email campaigns since our deliverability issues were fixed.

What do you dislike about Folderly?

Can’t tell anything. We enjoy working with Folderly.

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

At some point, we faced the problem of poor stats in our email outreach campaigns. Despite the internal efforts, our emails were getting into the spam or promotion folders. Despite a price higher than the average on the market, their software is worth the money. The support team plays a significant role here. They have helped to set up all the DNS records at the beginning. After that we just had an overview in the dashboard on a weekly basis. The tool works for you and doesn't need big-time involvement, we were just tracking improvements in our deliverability rates.

What do you like best about Folderly?

Folderly is a working tool that helps to solve all ranges of email deliverability problems. The platform is intuitive and quite easy to use. Everything is shown on the dashboard. To mention, I appreciated the enthusiastic work of Daria from the customer success team. She helped with the process and was always there for us to have all the updates and questions answered.

What do you dislike about Folderly?

Didn’t see anything to dislike, everything is ok

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

The goal for us was to improve deliverability of our email campaigns and get them out of spam and promotion folders to the inbox. We have definitely solved our problems with Folderly. Our mailboxes are warmed up, SPF, DKIM and DMARC records are reset correctly, deliverability increased so we have high open and reply rates.

After setup, spam testing is automated, and the result shows on the dashboard. Their human support was outstanding! Folderly is a one-stop shop for your spam detection and resolution.

What do you dislike about Folderly?

Spam is a significant obstacle to productivity. Even google support was unable to fix it. The main benefit is the continuous spam check and fixing once you subscribe to the service.

"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.
