Mailwarm

Mailwarm is an email warm up tool that is backed by Y Combinator. It improves the warm up of an email while improving the sender's reputation and email deliverability so that you can always reach the inbox.

Mailbomb pricing starts at $79 per month if you are billing monthly; annually it starts at $69 per month. You can send up to 50 emails per day and do one account for warm up.

It also comes with live tracking and real-time monitoring for testing where your emails are actually landing.

Most people don't do warm-up because it takes up to 1 to 2 weeks but it is essential if you want to have deliverability of up to 90%.

If you will send a high volume of emails, deliverability matters. If you are landing in spam and all your emails are worthless, you are basically spending money on something that is not going to get results.

Mailwarm is a perfect tool for freelancers, businesses who are sending a minimum of 10,000 emails per month.

Backed by 15+ years of email expertise, Mailwarm automatically builds your sender reputation by interacting with your emails the way real prospects would opening them, marking them as important, replying to them, and moving them out of spam.

Every warmup email sent through Mailwarm generates 5 positive interactions, which sends the right signals to Gmail, Outlook, and other email providers that your account is trustworthy and worth delivering to the primary inbox.

Setting up Mailwarm takes under 2 minutes. You connect your email account, start the warmer, and the platform handles everything else on autopilot.

It works with Gmail, Google Workspace, Outlook, Yahoo, Zoho, SendGrid, Mailgun, AWS, and any other SMTP-based platform, making it one of the most flexible warmup tools available.

On top of daily warmup activity, Mailwarm also runs continuous 24/7 inbox placement tests so you can see live whether your emails are landing in inbox or spam per mailbox and per SMTP and catch deliverability issues before they tank your campaigns.
