Custom fields

Last updated on Oct 26, 2026

Custom contact fields let you store extra information about your contacts that is not included by default. You can use these fields to keep your data organized and to personalize your emails using custom variables.

Reply currently supports two types of custom fields:

  • Text fields for words or short phrases
  • Number fields for numeric values only

The number of custom fields you can create depends on your account. New accounts can create up to 200 custom fields. These fields are shared with all team members.

The limit counts every custom field, whatever its type or where it was created. When you add a field, the New custom field window shows how many more you can add.

đź’ˇImportant: Number fields accept only numbers. Text values are not supported.

đź’ˇA custom field value can hold up to 4,000 characters. Longer values are cut. Values generated by AI are limited to 1,500 characters.

If you need more custom fields than your account allows, please contact our support team via chat or at [email protected].
