Email deliverability is a significant concern when you are doing cold email outreach.

With new email accounts aren’t warmed up, it’s necessary to send a limited number of emails during the first days. This is the process of teaching email servers that you’re a legitimate sender.

While we also don’t offer an email warmup tool, you can find how to warm up an email account in this guide.

It will give you many examples and tips on how to send emails to prevent possible blocks. If you have some specific questions after going through it, reach out via chat or email contact@hunter.io and we’d be happy to help.
