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

Warmup Inbox : how it works ?

Warmup Inbox works in a relatively similar way to MailReach but it only does a small part of what MailReach offers to improve the results of email campaigns.
Warmup Inbox is an email warm up software that sends emails from your inbox to a pool of 7000+ email addresses and get replies and engagement from these addresses.
Their warm up is basic and the emails don’t mean anything (which can be suspicious to the big providers like Google and Microsoft who can easily understand it is gibberish).
Warmup Inbox basically sends emails and gets engagement but there’s apparently no smartness in the warming behavior which limits the efficiency of using such tool.
Also, Warmup Inbox includes the same code in each subject line to help filtering the emails. This is also an obvious element that does not help build trust with email providers.
Conclusion: Warmup Inbox can have a positive impact on your deliverability, but the behavior is too basic and not enough “human” to build trust with email providers.
The features are also very limited : no spam checker, no blacklist and DNS monitoring.

How MailReach works?

MailReach can look similar to Warmup Inbox but there are big differences in terms of warming behavior, features and value brought to improve deliverability and email results.
MailReach uses your email account to exchange emails with a network of more than 10 000 high reputation addresses.
Each email sent from your inbox is meaningful to build trust with email providers which are able to suggest smart/quick replies to the warming emails. The replies are positive too, which is important.
MailReach generates positive interaction to the email activity by opening the emails, marking them as important, removing from spam and categories and replying positively.
A big difference with Warmup Inbox is MailReach’s smart algorithm that constantly optimizes your activity to maximize the efficiency of the warming.
For instance, if MailReach detects a spam spike, it will make you engage with the highest reputation email addresses in the network to recover your deliverability as soon as possible.
Also, MailReach offer a powerful email spam test to optimize your copy and sending setup to have the greatest deliverability possible.
TL;DR: MailReach is a concrete email deliverability solution that has been developed to maximize your deliverability by taking a lot of factors into account, including a smart warming algorithm with the most human and trustful email activity.

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.
