When a cold email goes unanswered, Striker sends three follow-ups on a specific schedule. Each one adds new information. The sequence ends with a clean breakup email that leaves the door open.

​
The sequence

Follow-upSend timingLengthRule
Day 33 days after cold emailMax 75 wordsNew value angle — case study, insight, or stat they haven’t seen
Day 55 days after cold emailMax 100 wordsCompletely different angle — different pain, different benefit
Day 77 days after cold emailMax 50 wordsBreakup email — polite, assumes no interest, leaves door open

Example sequence

Day 3: 
Subject: Re: Your Series B + the ops bottleneck

One more angle: teams that implement this in Q2 typically
see the ops team handle 3x the volume by Q4 without new hires.

Happened with a similar-sized B2B SaaS team in SF last quarter.

Still worth 20 minutes?
Day 5: 
Subject: Re: Your Series B + the ops bottleneck

Different angle: the real cost isn't the ops work itself,
it's the senior time spent doing it. Your Series B probably
doubled the leadership workload without doubling the team.

We fix the senior time problem specifically. Different from
general ops tooling.

Open to a 15-minute call this week to see if it fits?
Day 7: 
Subject: Re: Your Series B + the ops bottleneck

Assuming the timing isn't right — totally fair.

I'll leave the door open if things change in Q3.

​
