How to warm up an IP Address

What does warming up an IP mean?

If you been doing any research about sending email in bulk for the first time, you probably heard the term "Warming up an IP." Newly assigned IP addresses that have never sent mail before have no email reputation attached to them. So when an ISP sees your IP for the first time, they are more cautious and they have "Spam Filters" in place to examine if your emails are spam or not. They may "Delay" or "Reject" your emails, if you are sending too much too fast from a new IP Address. So it's important to warm up your IP and gradually increase your send rate through those IP address, which is also known as Throttling.

How do I warm up my IP Address?

You'll see suggestions all over the web, you'll see services that will help you warm your IP's also known as (Email Throttling). Where they collect all the emails and release them slowly to the different ISP's - Some emails will take hours to be sent.

So here are some suggestions based on different scenarios:

For a new business - Let it happen naturally, you're not going to have a million customers overnight and if you do please contact me and share your secrets.

For an existing business - When you switch IP's or add a new mail server, don't switch all at once, split the load and gradually increase the load on the new IP over a period of 30 days - until you're at your max send rate.

For a new email list - Sometimes, you have the opportunity to buy a legit mailing list of a company that went out of business or some other means. Now you have millions of new potential customers. You want to send an email to all those new potential customers. What do you do? You need to warm up your IP's, by sending emails through your IP and gradually increase the load. Or use a mailing service like Sendgrid - who already have warmed up IP's in place. I'm plugging Sendgrid, because they did an amazing job putting together this must watch video on "Warming Up an IP Address."
