Does email warmup work?

Yes, email warmup is effective when it aligns with your sending strategy. It allows your email account to build a positive reputation with email service providers (ESPs) by starting with small sends and increasing volume gradually. This process helps ensure better inbox placement, reducing the chances of your messages getting flagged as spam.
Why email warmup is important:

1. Prevents spam flags: Sending a large number of emails immediately from a new or inactive account can trigger spam filters. Warmup helps avoid this by mimicking regular user behavior.
2. Improves deliverability: Warmup allows for better inbox placement by showing ESPs that the email address is active and trustworthy, increasing open and response rates over time.
3. Builds sender reputation: Establishing a positive reputation with ESPs ensures your emails continue to reach recipients, which is critical for outreach and marketing campaigns.

Recommended warmup practices:

• Start small: Begin by sending 10-20 emails daily, gradually increasing volume over several weeks.
• Use real engagement: Aim for replies and clicks on your warmup emails to boost credibility with ESPs.
