How do I map contact fields during import?

Updated Nov 2, 2026

In the Map your CSV columns step, each MailRush field has a list of your columns (Column 1 to Column 10, with your header name).

Steps

  1. For each field you want to fill, choose the column that holds it: FirstName, LastName, Title, Company, Email, Phone and custom1 to custom6.
  2. Always map Email.
  3. Leave fields you do not need on Select Column. Unmapped columns are ignored.
  4. Click Next: Assign Tags.

Good to know

  • Header names containing firstname, lastname, email, title, company or phone are matched automatically. Check every selection anyway.
  • Use custom1 to custom6 for anything else you want to personalize with, such as a city or a pain point, then use {{custom1}} in your emails.
