Folderly’s marketing has been great.

Credit where it’s due. Folderly is simple enough to use and they’ve marketed their product right.

But it’s not enough for those who need real, actionable results.

Capped reply rates: They cap the reply rate for the warming emails. For the basic plan, they only offer 25%—which is not enough to improve your sender reputation.
Low daily email allowance: Warmup Inbox’s basic plan only allows 75 warming emails per day.
Limited spam testing & deliverability insights: No inbox placement or comprehensive spam tracking.
Cosmetic feature add-ons: You get to warm templates and choose your warmup topic—but these features do not actually improve your sender reputation.  They can hurt your deliverability if they don’t align with email best practices.

MailReach outperforms Warmup Inbox where it counts.

Uncapped Reply Rates

Mailreach gets you a perfect reply rate to help maximize the sender reputation. There are no caps on the rate— it’s always more than 50% and randomized to mimic a human behavior.

Meaningful warmup content

MailReach allows up to 100 warming emails daily. We use your email account to exchange emails with a network of 30k+ high-reputation inboxes.

In-depth Inbox & Spam Testing

Track sender reputation by provider, get unbiased spam testing, and monitor all deliverability insights directly.

More reasons to choose MailReach for email deliverability.

Are Folderly and MailReach legit?

Folderly and MailReach are email automation solutions designed to warm up email addresses and associated domains.
As Folderly and MailReach are email automation solutions, they need to be connected to a mailbox and be able to open and send emails, reply, mark as important, remove from spam and categories, archive, etc.
The customers give the authorization to these tools to do all these actions. These actions can be done using the official Google or Microsoft API or via SMTP.
Given the above, email warming tools like Folderly or MailReach are using regular email automation protocols to make thousands of inboxes exchange emails, open them, mark some as important, remove from spam, etc.

Folderly vs MailReach: is there really a price difference?

MailReach is 8 times less expensive than Folderly with the same features to help you improve your deliverability and with a more reliable email spam test.
Bonus: in the comparison with Folderly, we don’t count the sliding scale pricing we offer which discounts the price as you add more email accounts to warm with us.

What is a warm email?

A warm email can mean several things. A warm email can be the opposite of a “cold email”, that means an email to someone who has already showed interest in your product or service or has already interacted with you or your business.
For others, a warm email can be a warming email, an email sent by an email warmup tool like MailReach or Mailwarm to generate engagement and raise your deliverability.

Why not choose a free email warm up tool?

Unfortunately, from what we’ve seen and based on feedback from our users, free email warmup tools have several problems.
Some of these problems are shared with paid warmup tools like Mailwarm as well.
For example, these tools use gibberish content in the emails (like Mailwarm) which is obviously fake and can be easily identified by the email providers.
Also, their behavior and features are very limited and this has an impact on the efficiency of these solutions.

Warmup Inbox’s limits can’t compete with MailReach’s performance.

Warmup Inbox may work, but MailReach offers a smarter, uncapped warmup solution that maximizes your sender reputation. Get real, powerful engagement and up to 100 warming emails per day—at a better value.
