Sounds good. Send me the proposal.
Because the silence usually starts before the proposal is sent.
You finish the call thinking it went well. The buyer asked sensible questions. They seemed interested. So you send the proposal.
Then the follow-ups begin.
I reviewed one call where the conversation ran for nearly an hour before the seller learned that a partner had to approve the decision. In another, the buyer liked the plan but still did not trust the execution because previous agencies had promised the same thing.
Those are different problems. Neither is fixed by a better “just checking in” message.
Before a proposal can help, the buyer needs clarity on the problem, the consequence of leaving it unresolved, why your approach fits, who needs to decide, and what happens next.
That is why another follow-up template is rarely the first fix.
