When warming an IP address, what is the maximum number of daily emails that are recommended during the first week?

When warming an IP address, it is essential to gradually increase the volume of emails sent to establish a positive sender reputation with Internet Service Providers (ISPs). The recommended practice during the first week is to start with a conservative number of emails to ensure engagement and minimize the likelihood of being marked as spam.

Starting with a maximum of 50,000 emails per day during the initial week allows for a manageable volume that can be monitored closely. This approach helps build the sender's reputation progressively, as the engagement rates of the emails sent can be assessed and optimized. It targets an appropriate balance, enabling the sender to gauge recipient responses and adjust the strategy as necessary.

As the sender progresses beyond the initial week, they can incrementally increase the number of daily emails based on positive recipient interactions, thereby enhancing their deliverability further. This method reflects best practices for ensuring a sustainable and trustworthy email marketing strategy.
