Getting Started with a Warm-up

Know more on the process of warming up a domain or an IP, which is the first step for all email senders.

About the Warm-up Process

Due to the high threat level associated with spammers who send mass emails and engage in other email-related criminal activities, inbox providers are cautious about new sending domains and IP addresses. To safeguard their users, these providers expect new, legitimate senders to demonstrate their trustworthiness.

An IP/domain warm-up process involves gradually increasing the email volume sent from a specific pair of domain and IP address over several days and getting positive feedback from recipients to establish a positive sending reputation with inbox providers.

A warm-up process will only have positive results if you:

Guidelines: Respect the senders guidelines documented by each inbox provider.
Engagement: Demonstrate your users are expecting the emails you send and interacting positively with them.

Conducting a proper IP and domain warm-up is essential for building a strong reputation with all email providers in the long run. This process significantly reduces the risk of having block/delay issues and increases the likelihood of reaching your users' primary inboxes.
