Top Email Warm-up Tools in 2021

by Gary Amaral in August 11th, 2021

The top reasons why businesses fail to pursue a great email campaign are predominantly the deliverability issues. There have been extended reports stating that as many as 20% of emails do not ideally reach the recipients’ inboxes. And, every time a new email address is used to send emails, the same gets blocked as soon as the campaigns begin. The problem lies in not using enough warmed-up addresses for the campaigns.

The domain warm-up service has become even more critical today ever since Google’s spam update came in 2019. To avoid the majority of the emails from getting marked as spam and ensuring smooth deliverability, email warming has become important. 

This blog will share more details on how to warm up the emails and top email warm-up tools of 2021 that would ensure seamless email deliverability.

What is an email warm-up?

The warm-up service for emails is a way to establish the new email account reputation and increase the email sending limit. The new account is used for cold emailing in smaller numbers and gradually increases the number each day. With every new account made, the senders get a daily email sending limit which you cannot use completely. To use this limit entirely, a user needs to build their good reputation step-by-step, which can only be achieved through a warm-up schedule to warm up your email.  

The ideal time to achieve full deliverability is 8-12 weeks. It might also get faster based on the emails sent or the volume and the engagement in the entire process.

How to warm up an account before sending cold emails?

You can send warm emails from the new email accounts by understanding the below processes:

Authenticating the account

A new email address calls for account authentication. It is how the email account is guarded against any SPAM filters and makes the email deliverability and cold email outreach successful. There are four major processes of authenticating the accounts:

  • SPF- The Sender Policy Framework is an authentication technique used to create a record of the account in the DNS. This is a list that holds all the authorized servers that can send a cold email.
  • DKIM- The Domain Keys Identified Mail is the authentication method that can help add a digital signature to the domain, preventing the emails from getting spoofed.
  • DMARC- The Domain-based Message Authentication, Reporting & Conformance records the SPF and DKIM data and assures the receiver’s ESP that the process is legitimate.
  • Custom Domain- This is a more authentic way to ensure the sender's reputation. It makes it more authentic while the recipients receive it. The links can be self-made, and custom domains can be attached with emails while sending them.

Sending individual emails

The ideal warm-up process starts with sending emails to the known contacts and building a sufficing conversation. 10-20 individual emails are a good thing to start by. There must also be consistent engagement following the emails to ensure that the email volume is being built and email outreach is improved. A long and engaging conversation is also helping you to authenticate your email account and make it ready for future campaigns. It is better to opt for writing personalized subject lines in this course to get a better reputation.

Maintaining conversation threads

To warm up your email is not just about getting replies but having meaningful engagement too. Having a conversation is important, but it might take about 8-12 weeks. To speed up the process, you can always add more email addresses to increase the inbound activities and your cold outreach. The better and more the conversation is, the better will the email sending quotas get to be. Then the accounts will become eligible to send bulk emails at a time.

Subscribing newsletters

There might be multiple newsletters from your business, but you need to have a minimum of 10-15 subscriptions of the same to authenticate your account. Get back to the inbox and ask for confirmation to help validate your email account. This will also help smoothen up the email inflow.

Maintaining email gaps

The emails have targeted algorithms to check how they are sent or received. To assure that you are not a robot, besides conducting the DNS warm-up, avoid sending many emails at once. The constant outflow of emails affects the sender’s domain reputation. The best way is to keep an ideal stop-gap between two consecutive cold emails that you are sending. This will also not trigger the spam filters unnecessarily.
