How do I import contacts and map fields in K2Mailer?

Open Contacts → Import Contacts, upload a CSV or delimited file, map the Email column plus any system or custom fields, choose one or more lists, and start the import. Existing unsubscribe, complaint, bounce, and suppression protections stay in force.

What are custom fields in email marketing?

Custom fields are extra contact data you define, such as company, city, plan, or renewal date. They personalize emails through shortcodes, power list-based segments, and can be collected through imports and web forms.

What is an email preference center?

It is the page subscribers reach from the unsubscribe link. They can save per-list preferences, unsubscribe from one list, or choose to unsubscribe from all marketing emails. Opening the page alone never unsubscribes anyone.
