What happens when you email 500 agencies across 41 countries and nobody replies (yet)

sent 152 personalized cold emails to marketing agencies across australia, uk, us, canada, new zealand, ireland, singapore, india, hong kong, and 20 other countries. queued another 378 more. total pipeline: 530 agencies.

replies so far: 3. one from hong kong asking for a demo. one from australia asking about pricing. one auto-response.

that's a 2% reply rate on the 152 that have been sent. the other 378 haven't gone out yet — gmail rate limited me at 93 in one day.

here's what i'm not doing: panicking.

2% reply rate on cold email is actually normal. some benchmarks say 1-5% is standard for B2B cold outreach. i'm in the range. the problem isn't the reply rate — it's the volume. 152 emails isn't enough data to draw conclusions. 530 will be.

what i've learned so far from the 3 replies:

the hong kong agency replied within 3 hours on a saturday. they asked about pricing and whether we could run a demo for one of their clients. asian agencies respond fast and are open to trying new services.

the australian agency asked "what exactly does the service include?" which tells me the pitch was intriguing enough to get a reply but not clear enough to close. i need to make the deliverables more concrete in the email.

the auto-response came from a uk agency's ticketing system. not a human reply but it means the email landed in their CRM, not spam. delivery is working.

what i'd change for the next 378:

make the first line even more specific — instead of "i found some opportunities on your site" say exactly what: "your homepage is missing alt text on 7 images and has no meta description on 3 pages"

add a one-line case study: "we helped [type of agency] generate 47 prospect conversations in their first month"

shorten the email to 4 lines max. agency owners are busy. every extra line is a reason to stop reading.

has anyone here gone through the "sent hundreds of emails with barely any replies" phase? what broke through for you?
