How long should I warm up email?

New email domains and IP addresses should warm up email for approximately one to three months. This period provides enough time to ramp up email sending and gradually improve the domain's reputation. You can shorten the time frame with the following practices: ensure your email server is configured correctly, avoid sending spammy content, and authenticate your emails.

What happens if I don’t warm up email?

If you don’t warm up email when using a new domain or IP address, your emails will likely be marked as spam. The reason for this is that the domain or IP doesn’t have an existing sender reputation.

Is email warmup legal?

Warmup uses a controlled network to safely warm up your email domain and IP without any risk. Compared to older API methods, Warmup is the most effective and reliable way to warm inboxes.

How can I improve my email sender reputation?

You can improve your email sender reputation by following these email deliverability best practices:

What is email credibility?

Email credibility, also referred to as sender reputation or email sender score, is an indicator of your email-sending habits, much like a credit score. If your emails perform poorly, are not secured, frequently bounce, or are marked as spam, you’ll have low email credibility. Conversely, maintaining a low bounce and spam complaint rate, authenticating your emails, and improving your email engagement will build email credibility.

How do Warmup seeds work?

Warmup emulates realistic email engagement behaviors that correlate to your existing or historical sending behaviors. By accounting for key factors, such as cultural norms, user behavior patterns with different browsers, and time zones, Warmup creates realistic engagement actions that look and feel authentic to email service providers.
