Invalid emails
-
Hey guys! We run an online jewelry store and noticed that every now and then a few invalid emails end up in our list. What’s the best way to clean those out so we’re not paying for contacts that aren’t even reachable, and so the list stays healthy overall?
And while we’re at it… any tips on how to stop invalid emails from sneaking into our audience in the first place?

Hi there,
Great question, keeping your list clean is one of the best things you can do for your deliverability, performance, and overall costs, so it’s smart to tackle this early.
1. Cleaning out invalid emails
Omnisend offers automated list cleaning, so you can remove invalid contacts in just a few clicks. This helps you:
- improve deliverability
- reduce bounce rates
- protect your sender reputation
- boost open and click rates
- get more accurate reporting
- reduce costs by not paying for unreachable contacts
- increase ROI across your marketing efforts
Invalid email addresses has a cumulative effect, so it’s best not to wait until issues become noticeable.
To run the cleaning, go to:
Reports → Deliverability → scroll to Email list hygiene → Go to email list cleaning
2. Preventing invalid emails from entering your list
To stop bad or mistyped addresses from getting into your audience in the first place, we strongly recommend enabling double opt-in. It confirms that the subscriber owns the email address and ensures your list only grows with valid, engaged contacts.
You can enable this under:
Behaviour settings → Audience management → Enable double opt-in
Omnisend also supports Google reCAPTCHA on signup forms, a widely used tool that helps block spam bots without adding friction for legitimate customers.
Both double opt-in and reCAPTCHA work together to keep your list clean from the start.
If you need any guidance while setting this up, feel free to reach out, we’re here to help you keep your audience healthy as you grow.
