Email Warmup

What is Email warmup?

Email warm-up is the process of preparing an email address, domain, or IP to build a positive email sending reputation with email providers and spam filters.

Email service providers such as Gmail, Outlook or Yahoo have implemented strong spam filters. They will check your emails for spam words, filter out anything that seems unsolicited and ensure that your email activity looks normal. If you start sending hundreds of emails from a brand-new email account, you will end up in spam pretty quickly.

Regardless of a google workspace subscription, you’ve got the boundary of sending a max of 2000 emails consistent with day. In case you simply made the email account, the gateway is even extra minimum. Email warm-up builds the credibility of being capable of sending greater emails.
To use it to its full potential, you have to build a good reputation, which can be done by email warm up.

Ideally, it takes 8-12 weeks to manage maximum deliverability. Depending on email volume and the session in the warm up process, the email gets ready faster. The email warmup may take a longer time than expect if the reciever engagement level is too low.

There are two ways to warm up your email account. Either you can do it manually or use a dedicated email warmup service that will do the job for you.

Email warmup: the manual way

It is a difficult process plus it takes a lot time to do.
If you have patience and time, manually warming up your email address works, but considering the quality of automated inbox warming tools available, manual email warming won’t be the best use of your time.
You’ll need to ensure the people you’re emailing are replying to you, and there’s real engagement in your email threads.

The Manual Way

Email warmup: using an email warmup service

Otherwise, you can use an email warmup service to do this process automatically.
There are numerous warmup services provided by different company and with different features and price, some email warmup services will make your address interact with other members from their user base, your account will be sending emails to other users and will reply to their incoming emails.

When it comes to the actual content email warm up tools send from your inbox, it varies depending on the service you use. Some warm up tools use human and unique email copy in each of your warming emails. Others will stuff the warming emails with random words that may look less natural.

How do I warm up my email?

Sending emails manually to your friends and co-workers to start a conversation is the first step in the email warming process. You should send 10-15 separate emails from the new email address at first. With more conversations, your email service provider becomes confident in your genuine actions and progressively prepares your email account for email campaigns.
