When a campaign underperforms, most teams rewrite the copy first. Copy is usually the fourth or fifth problem, not the first. Here is the order we actually check.
1. Is it arriving?
Before anything else, confirm delivery. Send seeded test messages into the major providers and check where they land. If a meaningful share is going to spam or promotions, nothing downstream matters. Fix authentication, warming and volume first.
2. Is the list right?
A good message to the wrong person reads like a bad message. Check three things: does the company genuinely have the problem you solve, is this person close enough to the problem to care, and is the record verified. A list built from a job title filter alone almost always underperforms one built from a behaviour or a signal.
3. Is the ask too big?
“Book a 30 minute demo” asks a stranger for half an hour. “Worth fourteen minutes on Thursday?” asks for a fraction of that and gives a concrete slot. Shrinking the ask is the fastest single lever we know.
4. Is the first line about them?
Open any underperforming sequence and count how many of the first ten words are about your company. If it is more than two, that is the problem. The opening line has one job: prove you did not send this to four thousand people.
5. Are you selling the product or the meeting?
Cold email does not close. It buys a conversation. Every feature you add to the message gives the reader another reason to decide no on their own. Say less, and leave the interesting part for the call.
6. Is the sequence too long or too short?
Single touch campaigns leave most of the pipeline unclaimed, because the majority of replies come from touches two to four. Eight touch campaigns burn the domain and the brand. Four is the range where the maths works.
What good looks like
Across Apex programmes, a healthy cold email campaign sits between five and nine percent reply rate once it is past calibration, with a bounce rate under two percent. If you are under two percent reply, the fault is almost never the verb in your subject line.
