Mailwarm Review: Why Email Experts Choose Folderly

There’s a lot of software promising to improve your email deliverability rates. But only a handful of products fix your email deliverability once and for all, rather than deliver marginal or temporary results.

Take a look at a comprehensive Mailwarm review before making a choice, and learn why Folderly, a comprehensive email deliverability platform, is a better choice for long-term results than warmup tools (to indeed rock inboxes in 2024).

Folderly vs Mailwarm: Comparison Table

While reviewing Mailwarm, we put it side-by-side with Folderly, a comprehensive email deliverability platform, so you can see the difference between email deliverability tools based on warmup and a comprehensive email deliverability fix.

Mailwarm vs Folderly: Core Features Compared 

Email warmup tools like Mailwarm do one thing: Progressively increase your inbox sending volumes with automatic email dispatches to owned email accounts. In theory, this increases your email sender reputation, which, in turn, increases the number of emails that land in the primary tab. 

In practice, however, email deliverability goes way beyond warmup. To ensure flawless email delivery, you also need to have the correct DNS settings, maintain a good IP reputation, and keep an eye on your email content. In contrast to Mailwarm, Folderly handles all aspects of email deliverability: Sender and domain reputation, email, infrastructure monitoring, and email content.

Email Deliverability Fix 

Your emails can end up in spam for a variety of reasons: low sender reputation, suboptimal email infrastructure configurations, or template content issues (check more non-intuitive reasons in our article Why your emails are going to spam).

Folderly fixes the entire spectrum of email deliverability problems. Mailwarm only applies one patch solution — increases your sender limits.

In the background, Folderly performs daily inbox upkeep, programmed by us to ensure ongoing sender reputation management. The upkeep cycle was originally tested and designed for our parent company, Belkins — one of the leading lead-gen agencies. Over the years, we further fine-tuned it, based on the feedback from mailbox providers and known spam traps to ensure organic, effective, IP and domain reputation management. 

If anything’s out of the ordinary, you’ll receive an instant alert with an issue description and recommendations for fixing things up, either directly in the app or on your email delivery platform. Our always-available customer success team can also help with all sorts of fixes on request. 😉

In contrast, Maliwarm only improves email deliverability through email warmups. You can schedule daily email dispatches to Mailwarm’s inbox network to increase your sending limits. Emails are capped at 50/200/500 per day depending on the plan.

Mailwarm’s algorithms will then perform automatic interactions — open, reply, mark as important — to send positive signals to the email provider. You can set a custom sending schedule and custom reply ratio (although 30% is recommended).

But here’s the thing: Higher sending limits per inbox don’t always translate to higher deliverability rates. 

There are 4 pillars that help to improve email deliverability: Sender reputation, recipient database, content quality, and proper infrastructure setup.

Mailwarm only addresses one element (and only to an extent) — sender reputation. By warming up an inbox, you can indeed progressively earn the good graces of ESPs. But you can easily mess things up.

If you mix up the sending limits and send a flood of emails in several hours, your reputation will get worse. Maliwarm also doesn’t provide any reports on inbox placement rates — so you just have to blindly trust that the tool is working. As one user mentioned, this may not always be the case: 

Other reviewers also mentioned that Mailwarm uses generic content for email warm-ups, which itself can trigger spam filters and land your emails into spam. 

Real-Time Deliverability Scores 

With Folderly, you can get real-time data on how you're hailing.

Your email deliverability score is based on your inbox rate, the number of detected spam triggers, and applied email deliverability best practices. You also get a 30-day overview of your deliverability stats across all tracked ESPs to understand how you’re hailing. 

Many new users start with a lower Folderly Score — but our platform helps raise email deliverability to 100% through a combination of manual and automatic actions aka everything we’ve mentioned in the previous section. 

Review inbox placement rates, segmenting all data by ESP. For example, you can benchmark Outlook 360 vs. Gmail deliverability rates or compare how different outreach templates perform. 

Mailwarm doesn’t provide any real-time scores or deliverability analytics. You only get daily progress reports on email warmups. 

Content Spam Triggers 

Folderly helps you identify spam triggers in emails with contextual insights. So that you can test and improve your email templates.

Our email spam word checker flags spammy word combos in your email and suggests better alternatives. Our algorithm was trained in the latest spam word lists and it’s frequently refreshed to produce even better results. (Btw, you can try spam words checker for free)

Folderly users benefit from more advanced spam content checks, done in the background. Learn exactly why your latest email went into spam and get advice on how to not have that happen ever again. 

Take it from Сhad Cornies, CEO of No Rules PR. Before Folderly, only 15% of Chad’s media outreach emails landed in the sender’s main inbox. Our Spam Trigger tool immediately helped Chad identify why his emails missed the mark: They were a bit too heavy on bold fonts, included spam words, and had a couple of more HTML-level problems. Plus, the company had incorrect SPF & DMARC record settings.

Once everything got fixed, No Rules PR email deliverability increased to 96% 🚀

Mailwarm doesn’t provide any tools for analyzing email content or detecting other email deliverability issues. Due to the lack of inbox placement tests and deliverability insights, you're left wondering if you're hitting spam triggers or not. 🤔

What Makes Folderly a Better Alternative to Mailwarm 

Folderly email deliverability platform is like a telescope. 🔭You can zoom in on every aspect of email deliverability and spot the tiniest issues. Mailwarm is more like using a pair of binoculars, you get the general view but may miss the finer details that can impact deliverability.

✅  Guaranteed Email Deliverability Fix

Mailwarm gives you the impression of some action: Email sent, interactions done, replies made. But you have no way to verify if Mailwarm is making a change to your scores without using another email deliverability tool to run an inbox placement test. 

Folderly provides real-time data on your sender reputation (Folderly Score), and inbox placement rates for all tracked ESPs. 

Additionally, we provide guidance on fixing spam triggers and implementing email deliverability best practices to help you improve your inbox health.

The combination of algorithmic and human expertise allows us to guarantee higher email deliverability — and we’ve got over two dozen case studies attesting to that claim! 

✅  Spam Trigger Detection

Folderly helps you diagnose the exact cause(s) of poor email deliverability rates aka the dreaded spam triggers.

We track four groups of spam triggers: domain, IP address, template, and mailbox, using signal data from email services providers — and report that back to you as contextual recommendations.

Mailwarm doesn’t provide any other analytics, beyond daily sending activity reports. 

✅ Access to Email Infrastructure Configuration Tools 

Proper DNS record configurations prevent spoofing and phishing, authenticate via SPF, DKIM, and DMARC, and contribute to senders’ trustworthiness. Misconfigurations or the absence of DNS records can cause email delivery issues or result in legitimate emails being marked as spam. 

Folderly automatically detects any issues with: 

• IMAP/SMTP configurations 

• DNS records configurations: SPF, DKIM, DMARC, BIMI

We also provide instructions for fixing those — or can have that part done for you as a white-glove service. 

Mailwarm doesn’t offer any tools for email infrastructure management. But hey, you can always use our DMARC generator or SPF generator for free.

Better Value for Money 

Mailwarm offers an attractive starter plan at $69/mo per inbox (with annual billing), which makes Folderly’s $120/mo starter price look higher.

But the thing is that both tools have different pricing models.

Mailwarm bills per number of sent emails and available data seats. At the Starter plan, you get only one seat, meaning that only one user can have access to your Mailwarm account.

Folderly, bills per inbox, not per user or per email sent. You can share access with several different users to collaborate on your email campaigns (We have a very cozy team space!). Folderly plan also hooks you up with more product features: Unlimited inbox placement tests, real-time deliverability analytics, sender reputation monitoring, spam trigger analysis, and more!

If you were to use Mailwarm’s lowest plan and pay extra for those extra tools separately, the total software costs would be 2X-4X higher than Folderly’s plans.

Folderly vs Mailwarm: Which Email Deliverability Platform to Choose? 

If you need a simple email warm-up tool with a fast setup process to boost the reputation of a new domain or inbox, Mailwarm claims it can do the trick (but doesn’t provide analytics to back this up).

But if you want to ensure ongoing email inbox health and maintain a strong sender reputation, Folderly is a better option.
