The Lemlist warm-up process is crucial for ensuring high deliverability and preventing email bounces. By gradually increasing the number of sent emails, it helps establish a positive sending reputation with email service providers (ESPs). This technique is essential for marketers and sales teams who rely on cold email campaigns to engage with prospects.

Here’s how the warm-up process works in practice:

  1. Start slow: Begin with a small number of emails sent per day and gradually increase the volume over time.
  2. Use real interactions: Send emails to actual contacts or use Lemlist’s AI-powered system to simulate realistic email exchanges.
  3. Monitor results: Keep track of open rates, reply rates, and bounce rates to adjust the warm-up process as needed.

Effective email warm-up helps to build trust with email service providers and minimizes the risk of ending up in spam folders.

Below is a table outlining the typical daily email sending schedule during the warm-up phase:

Day Emails Sent
Day 1 5-10
Day 2-3 15-25
Day 4-5 30-50
Day 6+ 50-100+
