You can never ensure a 0% bounce rate, but there's a lot you can do to prevent your emails from bouncing back and improve your deliverability as a whole.
We highly recommend you take these technical but necessary steps before launching campaigns:
- Set your verification level: According to your choice, Prospect.io will check -or not- the validity of the email addresses that you upload into the app.
- Configure a CNAME for click tracking (only for account administrators): By configuring a subdomain for click tracking, you don't have to share a common tracking IP whose reputation might have been harmed by other, less careful users.
- Configuring your DKIM and SPF records to authenticate yourself as the owner of the domain name from which you send emails.
