Email deliverability questions? Ask the experts (that’s us).

How long do you have to warm up emails?

At least 14 days if it’s a brand-new domain or mailbox, and no campaigns during that time. This helps build a strong sender reputation from the start.
But email warmup doesn’t stop there. It's not a one-and-done step. To protect and maintain your reputation, you should keep warming your mailbox while you’re sending campaigns and even between them. The key is to sustain consistent, positive engagement, which is what tells email providers that you’re a trustworthy sender long-term.

Do email warmup tools work?

They do! And if you’re sending B2B cold emails, they’re non-negotiable. Warmup tools run real conversations between your inbox and others, racking up opens, replies, and positive signals. To Gmail or Outlook, that looks like you’re a reliable B2B sender, not a spammer.

What is the best email warmup tool?

The best email warmup tool is one that doesn’t just “fake it” but actually builds trust with inbox providers. That’s why teams choose MailReach.
Unlike most alternatives, MailReach focuses on B2B cold email needs. We do it by creating authentic conversations with Gmail (Google Workspace) and Outlook (O365) accounts, boosting deliverability with an email warmup network of 30K mailboxes, and keeping your reputation strong so your emails land in the inbox where they belong.

Why is email warmup important?

Because even the best campaigns flop when no one sees them. Your sender reputation decides whether you hit the inbox or spam.
Reputation is built on engagement: opens, replies, stars, and other positive signals. An email warmup tool like MailReach helps you by generating these interactions before you start your campaigns and while they’re running.
