Folderly helped us a lot to save our emails from spam, so now we don't need to worry about deliverability at all. We check our account on a daily basis to make sure we're aware of any pitfalls that may occur. Actually, everything works great, communication with Folderly was on the top level. Customer Success Managers are always willing to help us. Definitely worth its money as every our email gets to the target.
  • Folderly fixes our deliverability issues
  • Folderly guard our domain reputation
  • Folderly gives advice on email content
  • Nothing to dislike, as we will use Folderly in the future and are open to the further cooperation with them.
Actually, everyone should have a tool like Folderly, because you might not even realize you have an issue with your emails going to spam. And resolving this problem on your own is really difficult. So, it's better to uncover deliverability issues early and repair them quickly than to lose money because your emails wind up in spam, without knowing you could make more.

In my experience, with these numbers in mind, you can fine-tune any campaign to perfection, and the customer success team at Folderly will give you enough advice to help you reach your goal.

I came up with the problem of our emails lending into spam which stopped all our ongoing marketing and sales campaigns. In the very first week, we made a few calls with the Folderly team; they provided a professional consultancy where we analyzed our case, defined the reason for the issues and got plenty of recommendations on how to avoid spam in the future. After that, Folderly spam fix solution helped us to cure our domain in the next 2 weeks.
  • Fixed the spam issue problem
  • Helped us to detect the reason of the problem
  • Provided recommendations and rules to follow to avoid the problem in the future

Great email deliverability testing feature. 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.
  • Email deliverability testing
  • Checking email placement for different email providers
  • Stats on all the blacklists and DNS
  • An outreach. Combining the existing set of features with email outreach would be great.
If you receive complaints that your recipients didn't get your emails, or you see a low delivery rate.

We use Folderly in several departments. The platform helped us to solve delivery pitfalls for several sales and marketing mailboxes. Sometimes we were getting replies that our emails were found in spam, so some business processes were holding.
  • Prevent emails from going to spam
  • Increase email sending volumes from a specific mailbox
  • Arrange domain infrastructure
  • An email verification feature. It would save time and money to combine those features in one tool.
The primary goal is to fix delivery and open rates. At the same time maintain domain health, and organize domain infrastructure. It's appropriate when your company relies on email marketing as a sales or retention channel.

The main issue was html marketing emails going to spam. We used several sending systems that offered email deliverability solution, but it never helped. Folderly helped to re-organize the structure our domains and subdomains, fix technical settings and shared practices abound sending process.
  • Testing of email landing folders
  • System of alerts
  • Auto achived warmup emails
  • Team or manager access
I would recommend using Folderly if you've ever heard that your emails land in spam. Very common issue for marketing emails that are overwhelmed with links, images, cta's. Or at least test what are the landing folders of your emails. it will help to recognise wether you have delivery troubles.

Folderly is used across the organization. Email campaigns are a significant part of our lead generation and gaining new customers, so we needed an all-in-one platform to take care of the reasons our emails land in spam.
  • Fix of tech issues: domain analysis, DNS, DMARC, SPF records were fixed ASAP
  • Spam filters check, advice on templates and content, list segmentation, etc.
  • Automation that helps improve reputation and trustability as a sender.
  • Fixing spam: our emails are not going to the spam folder, but the inbox.
  • There's space for new features.
It is a great fit when you need to send emails not only internally in your company, but you’re reaching a number of clients, customers, prospects externally. Especially, when you have cold outreach campaigns.

It is used by the marketing, sales and business development departments, they send most of the emails.
  • Approach of customer support
  • Complex analysis of spam issues
  • Non-stop warm-up process and dynamic senders
  • Pricing higher than the average on the market
It is appropriate if you’re sending emails to your clients, customers, prospects, and marketing emails. 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.

It was an initiative of the sales team and is managed by our marketing department.
  • API integration
  • Domain analysis
  • DNS records check and fix
  • Using dynamic senders for warming up the domain
  • No ideas yet
In our case, 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.

Folderly helps us keep our emails in the inbox folder. At some point, we had poor deliverability stats, so our prospects couldn’t receive our emails. Since signing up, we have a good sender reputation and deliverability rates — consequently, higher engagement rates and better results for our campaigns.
  • The tool is automated, and it doesn't need great time involvement
  • We are easily tracking our results in the dashboard
  • The support team is very responsive and responsible
  • The setting up process was a big challenging
If you send email campaigns regularly you might need this tool, otherwise sooner or later you will be trapped in spam folder.

Folderly fixed my spam issues! After setup, spam testing is automated, and the result shows on the dashboard. Their human support was outstanding! It's being used across the company.
  • Check for spam by automatically sending emails and responses.
  • Displays a send score.
  • Provides continuous check and stats.
  • The initial setup may be a bit complex for a first-time, not technical user. That being said, Folderly support mitigates that until onboarding gets completed.
When you don't get a response to emails, start getting worried. It probably means your emails land in a spam folder. Resolving this is tough, and Folderly does an excellent job!
