Writing an AI email prompt

Picking a saved prompt, choosing B2C or B2B, loading a real contact, editing the Pre Prompt and Rules, generating a sample email in Results, saving the prompt, and choosing it in an email blast.

With an AI email blast, Bigly writes a personal subject and body for every contact instead of sending the same template to everyone. The Email Prompt tab is where you write the instructions the AI follows and test them on real contacts before you send anything.

Before you start

  • Have at least one contact with useful details, such as name, company and title, so you can test against it.
  • Set up your email signature. It's added to AI emails when they're sent.

Open a prompt

  1. Go to AI › Email Prompt.
  2. Click one of your saved prompts to open it.

Test a prompt on a contact

  1. Choose B2C (selling to consumers) or B2B (selling to businesses).
  2. In Search Contacts, start typing a contact's name and pick them. The Payload box fills in with that contact's details.
  3. Edit the Pre Prompt: the main instructions, such as who you are, what you offer, and the tone to use.
  4. Edit the Rules: the do's and don'ts, such as length limits or words to avoid.
  5. Click Submit. After a moment, a sample email appears under Results, with a Subject and Body. Nothing is sent to the contact.
  6. Adjust the Pre Prompt or Rules and click Submit again until you're happy.

Common questions

It says "Please fill the payload". Pick a contact in Search Contacts first.

Does Submit send an email? No. It only shows you a preview.

How do I know the emails will read well? Each contact's email is written by the AI when the blast sends, so test your prompt on a few different contacts first.
