Frequently asked questions

What is a good email bounce rate?

Below about 2% is generally considered healthy. Above that, clean your list and check your sending setup, because high bounces damage your reputation.

How do I reduce email bounces?

Use confirmed opt-in, remove invalid and inactive addresses, and authenticate your domain. A clean, engaged list bounces far less.

How do I keep good deliverability?

On Klairova you can grow an owned, engaged audience and send with proper authentication, so your emails land where they should.
