Domain warming is the process of preparing email servers to accept email from a new or little-used email domain. This usually involves sending a series of test emails to the new domain to make sure that it is properly configured to receive email. Domain warming can help prevent email deliverability problems when a new email domain is launched. There are several steps that can be taken during domain warming: 1) Verify DNS settings: Make sure that the new email domain has proper DNS settings for mail exchange (MX) and sender policy framework (SPF). These settings need to be in place before email can be delivered to the new domain. 2) Send test emails: Once the DNS settings are verified, start sending test emails to the new email domain. This will help identify any potential email deliverability problems. 3) Monitor email delivery: closely monitor email delivery to the new email domain. This will help identify any potential deliverability problems so that they can be fixed before launching the new email domain. 4) Launch the new email domain: Once all of the above steps have been completed, the new email domain can be launched.

There are several benefits to domain warming, including:

- improved email deliverability;

- increased email engagement (open rates, click-through rates, etc.); and

- a reduced chance of being flagged as spam.

Domain warming can take some time and effort, but the results are worth it.

Domain warming is the process of introducing a new domain name to an email ecosystem in order to establish a reputation and avoid spam filters. The three main types of domain warming are: gradual, aggressive, and hybrid.

Gradual domain warming means sending a low volume of emails over an extended period of time. This strategy is often used when there is a low risk of the domain being flagged as spam.

Aggressive domain warming means sending a high volume of emails in a short period of time. This strategy is often used when there is a higher risk of the domain being flagged as spam.

Hybrid domain warming is a combination of the two previous strategies and involves sending a moderate volume of emails over a moderate period of time. This strategy is often used when there is a moderate risk of the domain being flagged as spam.

It takes around 30-45 days to fully warm up a domain, though you may start seeing results after 10-15 email sends. During the first few email sends, monitor your metrics closely to ensure that your email program is having the desired effect. If you don't see results after a few email sends, consider changing your approach.

It can take up to 72 hours for email servers to recognize a new domain name. This process, called "propagation," is the time it takes for DNS changes to take effect. During propagation, email sent to your new domain name may not be delivered. Once propagation is complete, email should flow smoothly to and from your new domain name.
