Let’s bust some myths (and spare you from spam).

Myth
You need to warm up specific templates.
Language affects sender reputation.
Warmup topic tags improve delivery.
Warmup volume alone will fix your reputation.
Reality
Warming up your own templates has no have any positive impact on your sender reputation. It can, in fact, be harmful. What matters is building trust with natural, varied messages. This is exactly what our AI does.
It doesn’t. Google and Microsoft don’t dock points for not using French, Spanish, or Swahili. What matters is the quality of engagement your emails receive and the quality of the warming pool.
Inbox providers care about trust signals and behavior, not whether you’re talking about SaaS trends or sales strategies.
More emails aren’t the answer if they’re badly structured or ignored. MailReach uses smart volume scaling tied to your domain’s health, so every email sent helps, not hurts.

Before you warm up, here’s everything you might be wondering.

How long should I use MailReach’s email warmer?

MailReach should be used before your campaigns, during your campaigns and between your campaigns to build and maintain a perfect sender reputation.
The initial warmup phase should last 14 days minimum. No campaigns should be sent during this phase. Once it’s done, it’s crucial to keep email warming as long as you send campaigns and between them.
Having a constant high engagement rate is what maintains your sender reputation in the long run.

Does MailReach work with all Email Service Providers?

MailReach works with any email service provider that supports SMTP.
Here are the most common providers: Gmail (Google Workspace), Outlook (Office 365), Zoho, Brevo, Mailjet, Mailgun, SendGrid, Amazon SES, Sparkpost, Ionos, OVH.

Is MailReach safe?

MailReach is the safest option compared to our competitors. Here’s why:
  • The warming activity and content is meaningful, human and subtle, yet super effective. Google and Microsoft suggest smart replies on our warming emails.
  • Unlike our competitors, we don’t include the same word or code in all subject lines of our warming emails.
  • MailReach follows all email providers’ rules.

Does MailReach warm my domain and IP or only my email address?

MailReach warms the email account, associated domain and associated IP behind.
However, if you have multiple sending addresses under one domain and/or under one IP, every address should be warmed in order to generate enough engagement on the domain and/or IP level.

I’m already landing in spam, can MailReach help me?

If you’re landing in spam because of a damaged reputation, MailReach’s email warmer can help you restore your sender reputation. Restoration is possible in 90% of cases.
If you’re landing in spam because of your email content and/or sending setup, our email spam test (Spam Checker) can help you spot the spam-triggering elements.
