Cold email warm up refers to the process of gradually introducing your email address to Gmail's algorithm by sending small batches of emails at first and then increasing the volume and frequency over time.
This helps establish a positive sending reputation with Gmail, allowing your emails to reach the primary inbox instead of being marked as spam.
Otherwise, Gmail's algorithm views your sudden upsurge of cold emails as spammy behavior, which impacts your deliverability.
Warming up your cold emails is important for several reasons. Firstly, it helps you to build authority with Gmail's algorithm by showing that you are a legitimate sender and not a spammer.
This ensures your emails have a better chance of reaching the primary inbox, and it allows you to test and refine your email content and subject lines before sending them out in bulk, improving your chances of success.
Begin by sending emails to a smaller group of subscribers before the main campaign. Gradually, increase the volume, frequency, and number of targets, which establishes your sending reputation with Gmail.
