Question : How Can I Edit a Contact Field?

A contact field stores a piece of information about a contact — first name, city, language, last purchase date, anything you need for personalization or segmentation. Mailpro ships with the standard fields (email, first name, last name, mobile, etc.) and lets you create up to 30 custom fields per account. Editing a field is fast, but choosing the right field type and structure up front saves a lot of headaches later.

Edit a field for one contact

1. Open Lists → Contacts, find the contact. 2. Click on the contact to open the detail card. 3. Click on the field you want to change — it becomes editable. 4. Type the new value. 5. Save. The change applies immediately and is reflected in the next campaign.

Edit a field for many contacts (bulk)

For tens or thousands of contacts, use the bulk edit. Filter or search the contacts you want, select them with the master checkbox, click Bulk action → Update field, pick the field and the new value, confirm. Mailpro processes the change in seconds and logs it in the audit trail.

Standard fields vs custom fields

Create or rename a custom field

Open Lists → Field manager. Click New field, give it a name (lowercase, no spaces — e.g. signup_source), pick the type (text, date, number, boolean) and save. The field is now available on every contact and every subscription form. To rename: click the field, change the label and save — the internal identifier stays the same so existing personalizations and segments keep working.

Use the field in personalization and segmentation

Once a field exists, you can: insert it in any email/SMS using the merge tag %%fieldname%%, filter contacts by it in a segment, trigger automations based on its value, and export it in CSV reports.

Field limits and best practices

Best practices: name fields in lowercase with underscores; document each field’s purpose in your team wiki; review and clean up unused fields once a year.
