Before you send out emails, it’s best to verify your email list to make sure that you have good list hygiene. According to research by Marketing Sherpa, the average B2B email list decays at a rate of 2.1% per month. This is an annualized rate of 22.5%. Which means as you grow your list over a year, 22.5% of those email addresses become invalid.
How to keep your email list clean:
- Avoid buying email lists or scraping email lists.
- Remove recipients who haven’t engaged with you.
- Buy a verifying tool like Kickbox.
- If you are sending emails internationally, make sure you comply with regional email legislation (CAN-SPAM, CASL etc)
