Build the Subscriber List
Subscribers are people, tags describe subscribers, custom fields store subscriber details, and segments choose who matches the rules today.
Overview
The subscriber list is more than a count. It is the group of people who may receive your emails. If you include the wrong subscribers, the campaign is wrong even if the design is excellent.
In Mailrith, subscribers store email addresses and profile data. Tags describe broad labels like customer, lead, webinar, or vip. Custom fields store subscriber details such as plan, city, birthday, company size, or last purchased product. Segments use rules to find subscribers who match those rules right now.
What to Check
- Use Subscribers to search for, review, and update individual people.
- Use Tags for simple labels that are easy to include or exclude.
- Use Custom Fields for subscriber data that changes from person to person.
- Use Segments when the subscriber group should update automatically from rules.
- Use Subscriber Imports and Exports carefully when you move a large list into or out of Mailrith.
Fix Common Issues
Free Mailbox Addresses
An email checker found a consumer mailbox domain such as Gmail, Outlook, Yahoo, iCloud, or Proton.
- Keep the address if the subscriber opted in and the subscriber list is for consumers.
- For B2B outreach, ask for a work email when the workflow needs company context.
- Do not automatically reject free mailbox addresses for newsletters or creator subscribers.
- Use tags or custom fields to separate personal-domain and work-domain subscribers if that difference affects campaigns.
