Personalizing cold emails at scale with custom fields

Everyone uses {{first_name}}. That's no longer personalization — it's the minimum. Real personalization references something specific to the person.

Collect one specific detail

Add a column to your list: a recent post they wrote, their city, a product they launched. Even one line of genuine context lifts reply rates noticeably.

Map it as a custom field

When you import a CSV or Google Sheet into AceMail, any column can become a custom field. Use it in templates as {{city}} or {{recent_post}}.

Preview with real contacts

Before sending, preview the template against actual contacts to catch blank fields or awkward phrasing. Then send a test to yourself.
