Consent
Clear permission someone gives you to send them email. It means they understand what they signed up for and have agreed to get messages from you.
Also known as Permission
Consent in email marketing means someone has clearly said yes to hearing from you. They know who you are and what kind of messages you will send. This agreement gives you a solid base for any future email you send.
Consent matters because it protects your deliverability and keeps you within the law. When people actually want your emails, they open more, click more, and complain less. That tells inbox providers you are trusted, which keeps your messages out of the spam folder.
A simple way to handle consent is to use clear checkboxes and short copy that explains what someone will get and how often. Store when and how they signed up in your system. If you have not emailed a contact in a long time, send a quick re opt in campaign so you can confirm they still want to hear from you.
