How often do you experiment with your cold email template? #BuildingInPublic

I was late to experiment and thought about it after my last 5 leads didn't turn out well.

Here are 4 learning so far I had while running cold email campaigns for https://www.reviewreels.app/, 👇

1/ Experiment often:
Always experiment, there is no time and space to experiment, it can be a changing a button placement or copy or even spacing. I was so late to realize this truth.

2/ Make it short:
Later to realize this sublime but powerful truth. Make your email short and crisp. People don't have time to read all your stories how do you come up with the idea?

3/ Subject line is king:
Make it irresistible but don't make cringe. Make it sensible and curious. Nowadays I am experimenting a lot with the subject line.

4/ Make a segmentation among the leads and write different CTA, Copy for all these segments.

I would love to know, what all things work for you in cold emailing?
