AI for email content generation: our complete workflow

AI is not replacing our email team — it is making them 3x more productive. Here is our complete AI-assisted workflow.

Ideation

We feed ChatGPT our content calendar, audience data, and past performance. It generates 20 campaign ideas, which we filter down to the best 5.

Subject lines

Brew's AI generates subject lines trained on our historical data. We A/B test AI vs human and AI wins ~60% of the time.

Body copy

AI writes first drafts that humans edit for brand voice and accuracy. This cuts writing time from 2 hours to 30 minutes per email.

Send optimization

AI optimizes send time per recipient and selects the best-performing content variant for each segment.

Total time savings: about 12 hours/week for our 3-person email team.
