Hey guys!

I’ve been experimenting with different outbound marketing strategies to target digital marketing agencies, specifically CEOs and founders, to promote an AI software. In the message, I invite them to test it out for free.

I ran two campaigns: one using only cold email and the other combining handwritten direct mail with email follow-ups. Here are the results:

Campaign 1: Cold email (3-email sequence)

• 200 prospects
• 22 responses (11%)
• 7 meetings booked (3.5%)

Campaign 2: Handwritten direct mail + 2 follow-up emails

• 33 prospects
• 3 responses (9%)
• 2 meetings booked (6%)

The handwritten letter approach seems more personalized and leads to better conversion rates for booked meetings (6% vs. 3.5%), but the small sample size (33 prospects) makes it hard to draw solid conclusions, I guess.

My Plan

This experiment got me thinking: I’d like to launch a lead generation agency to help B2B companies get meetings with their dream clients. My focus would be on sending personalized physical objects—like handwritten letters—as the first touchpoint, followed by other outreach strategies.

I’m wondering:

• Should I increase the number of prospects contacted with handwritten direct mail to 100 to validate the results?
• Do you think this approach is scalable and worth investing in compared to traditional email outreach?
• Have you ever tried using personalized physical objects for outbound marketing? If so, what worked for you?

Your feedback would be very appreciated! Thank you :)
