Hi Steve,
You can build a workflow that writes personalized icebreakers/introductions for your cold email campaigns in bulk (attached example screenshot from one of my campaigns). I send around 4.3k emails per week, and the entire process is automated. Below is what it looks like:
Get leads from Apify scraper
Exports the CSV into Google Sheets
Adds a personalized icebreaker for each person
You only give the details about the leads you want, and the rest is automated.
You can also automate the copywriting part, but I prefer writing it manually as that is the most important part.
Hope this helps.
