Before you hit send on your next big email marketing campaign, there is one step you should not skip: sending a hygiene email.
What Is a Hygiene Email?
A hygiene email is sent to people who have not engaged with your emails in six months or more, along with contacts who may be on your list but have never received an email from your business. Think of it as a friendly reintroduction. You remind them who you are, explain the value you offer, and ask them to confirm whether they want to keep hearing from you.
Why Email List Hygiene Matters
Why does this matter? Because sending emails to a cold, outdated, or inactive list can hurt your results fast. Email providers like Gmail are paying close attention to sender behavior. Google recommends keeping spam complaint rates below 0.1% and avoiding rates of 0.3% or higher. If your list includes bad addresses, inactive users, or people who no longer recognize your brand, your emails are more likely to bounce, get ignored, or be marked as spam.
That can damage your sender reputation, which affects whether future emails land in the inbox or disappear into the spam folder. Even a small increase in your bounce rate can signal to email providers that your list is not healthy. And once your domain reputation takes a hit, it can take time and strategy to rebuild.
A hygiene email also helps keep costs under control. Platforms like Mailchimp base pricing on audience size and contact limits, so keeping inactive or uninterested subscribers on your list can mean paying for people who are not engaging. Cleaning your list helps you focus your budget on the people most likely to open, click, book, buy, or respond.
What to Include in a Hygiene Email
A strong hygiene email should be simple and direct. Reintroduce your business, explain what kind of content subscribers can expect, highlight the benefits of staying connected, and include a clear opt-in button or link. This gives your audience control while helping you build a cleaner, more engaged email list.
