Proposal follow-up — when to write, and what to say instead of "just checking in"

"Just checking in on the proposal I sent" is the most frequently written sentence in B2B sales and simultaneously the most useless. Not because it is impolite. Because it carries no information — and it carries none because the sender has none.

This piece is about where to get the information, so that you never have to write that sentence.

Why calendar-driven follow-up does not work

The standard sequence: day 3 — a nudge, day 7 — a call, day 14 — "one last question". The problem is that the calendar measures your impatience, not the client's decision process.

In typical B2B the decision involves six to ten stakeholders (Gartner), and the meetings where such things get approved happen every two weeks or once a month. Your day 3 lands in the middle of a week where nobody has opened the attachment yet. Your day 14 might land two days after the meeting where the decision was deferred for want of one piece of information — the one you could have supplied, if you had known.

There is also an asymmetry that is easy to forget: to you this is the proposal, the one from five days ago. To the client it is one of seven things this week.

Three signals that turn guessing into responding

Instead of counting days, respond to what is actually happening. There are three signals, and each leads to a different message.

1. The client came back to the proposal

The strongest signal there is. A second open after a few days means the topic returned to the table — someone asked about it, someone forwarded it, or the client is preparing for an internal conversation.

What to write: reference the section they spent the most time in. If it was pricing, write about scope options. If it was the timeline, write about the start date.

"I saw the topic came back around. If a side-by-side of what exactly separates the base and extended options in numbers would help, I'll have it ready tomorrow — it's one page on our side."

This works because it answers the question the client is actually asking themselves, rather than asking them whether they have decided.

2. Someone new is reading it

When you see visits from a different context than the original, it usually means the material has travelled inside the client's organization. This is the best moment in the entire process, because your proposal has started working without you — and that is exactly when it needs the most help.

What to write: offer a conversation with whoever joined, and say up front which questions you are ready for.

"If the proposal has reached people who weren't on our call, I'm happy to take technical questions in 20 minutes — the same three usually come up: integration with the current system, what happens when scope changes, and who runs the project on our side."

3. Silence after an open

The client opened the proposal, read it through, and did not reply. That is rarely disinterest — it is usually a specific missing piece they do not feel like articulating in an email.

What to write: state a hypothesis and give an easy exit. People answer a sentence they can confirm or deny far more readily than an open question.

"My guess is the open question is either budget for this quarter or the start date. If I got one of those right, I have a proposal for both situations. If not — one line about what the blocker is and I'll adjust."

The rule that saves most follow-ups

Every follow-up has to deliver something new. Anything: information, a document, a simplification, an answer to a question the client did not ask out loud. If the message contains nothing new, it is a nudge — and a nudge pushes the obligation to act onto the client while telling them you have nothing to add.

A practical test before sending: would this message be useful even if they never buy? If yes, send it. If no, you have not written it yet.

What not to do

• Do not claim the proposal "expires soon" if it does not. In B2B, where several people decide, artificial urgency does not accelerate anything — it irritates, and often removes you from consideration next time.
• Do not count opens out loud. "I see you've opened the proposal three times" is technically true and socially awful. Reading data is for choosing the topic and the moment, not for confrontation.
• Do not send "bumping this". That is a message purely about your calendar.
• Do not open with an apology. "Sorry to bother you" lowers your position and suggests you do not believe in the value of your own message.

How to get those signals if you send PDFs

Briefly: you cannot. An attachment reports nothing, so your only feedback is the client's reply or its absence.

Two ways out. First — send the proposal as a page at a link, and all three signals appear on their own. Second, if the format is imposed for some reason — deliberately engineer a signal into the content: end the proposal with a single question that can be answered in one sentence. It is a much weaker instrument, but better than nothing, because at least the absence of an answer means something.

I wrote separately about what the format actually changes: PDF or web page.

When to stop

A healthy rule: three messages that carry value, then one that closes. The closing one is not an ultimatum, just a polite tidying-up:

"I'm assuming this isn't a priority right now — completely understandable. I'll close it on my side so it stops cluttering your inbox. If it comes back in the autumn, the proposal still stands and one line is enough."

This message has the highest reply rate of the whole sequence, and that is not an accident. It removes pressure, it is honest, and it leaves the door open without asking for anything.

In short

Follow-up is only hard when you have no information. When you know the client came back to the proposal and stopped at pricing, the message writes itself and nobody has to "just check in". The entire job is having that information in the first place — which is a decision about proposal format, not about sales technique.
