Don't Land in the Spam Box, Ever (Email Warmup Tools & Tips Inside)

Don't Land in the Spam Box, Ever (Email Warmup Tools & Tips Inside)

Cold emails are the secret ingredient in your recipe for outreach success. But you can’t just keep sending a thousand emails without risking your domain reputation.

Sure, you have a great email outreach campaign planned out with compelling subject lines and customized first lines. But none of these will matter if your emails aren’t reaching the inboxes of your potential customers.

Even though email deliverability depends on a bunch of factors, the most important of them all is your sending reputation. That’s when email warmups come into the picture.

What’s Email Warmup, and Why the Hype?

Let’s assume a real-life scenario. Say you have a cold email campaign planned for your new SaaS product. You send 400 emails/ day to your leads. But nothing happens. You don’t hear back.
On investigation, your email deliverability tool tells you they have been landing in your prospects’ spam boxes all this while! 

Low engagement rates in emails trigger the spam police and risk your domain reputation. You could even be blacklisted!

And that’s the biggest danger of outreach - the spam box. Accounts get blacklisted if they keep sending a large number of emails without getting the optimal response rate because ESPs identify you as a spammer.

Email warmup is then your knight in shining armor. 

It stops your emails from getting marked as spam and sends and responds to emails automatically to force you into the primary inbox. With email warmup, you increase the chances of your prospects receiving and responding to your emails.

Email warmup helps you avoid the spam box by:

  • Boosting your sender reputation to ESPs (Email Service Providers),

  • Improving your deliverability rate, and

  • Ramping up the sending limit.

An effective email warmup strategy helps you to gradually increase your email sends per day without triggering the spam filters. ESPs are now extra tough on accounts while assessing their reputation. They keep a tab on your email open rates, response rates, and reactions – whether your emails are being marked important, ignored, deleted, or sent to spam.

In other words, ESPs see if you are giving enough value to your recipients through your emails.

And the easiest way to maintain a positive sender reputation is to set up automated warmups.
