What actually decides a reply
Cold email fails in three distinct places, and it is worth knowing which one you have. It can fail to arrive (deliverability), fail to be opened (subject line), or fail to be answered (body and ask). This scores all three.
The template smell
Phrases like "I hope this email finds you well" and "industry-leading solution" are recognised instantly as automated. They are not offensive; they are just evidence that the sender has written the same email to a thousand people, which tells the reader they can safely ignore it.
Ask for a reply, not a meeting
The most common structural mistake is asking a stranger for thirty minutes in the first email. It is a large commitment offered before any value has been established. Asking a question that can be answered in one line converts far better, and the meeting follows from the conversation rather than replacing it.
Length
Fifty to 125 words. Reply rates drop sharply past 150. If your email needs more than that, the problem is usually that it is trying to explain the product rather than earn a conversation.
Questions
Does the spam-word check guarantee inbox placement?
No. Deliverability depends mostly on domain reputation, authentication (SPF, DKIM, DMARC), sending volume and warm-up. Content is the last mile, not the whole road.
How much personalisation is enough?
A merge tag is the floor and is barely personalisation at all. One genuine, specific observation about the company outperforms any amount of templated variable substitution.
What reply rate should I expect?
Five to ten percent for well-targeted cold B2B outbound. Under two percent usually means a targeting problem rather than a copy problem.
Should I include a link?
One at most, and ideally none in the first email. Multiple links hurt deliverability and give the reader an easy alternative to replying.
