best follow up email after sending proposal

You've sent the proposal and one follow-up with no reply. Here's what the research actually says about timing, persistence, and what to write next.

How long should I wait before sending my second follow-up on a proposal?

Wait 5–7 days after your first follow-up before sending the second one, then space subsequent touches about 1–2 weeks apart. The goal is to stay top-of-mind without becoming a nuisance — and always lead with context about who you are and why you're reaching out again.

How many follow-ups should I send before giving up on a proposal?

Research cited by Brevet (via Smartlead) suggests most sales require at least five follow-ups after the initial contact — so sending two or three and stopping is almost certainly too early. Consider sending a final 'break-up' email after 3–5 unanswered follow-ups that leaves the door open for future conversations.

Should I use channels other than email to follow up on a proposal?

Yes — if email alone isn't getting a response after two or three attempts, add a LinkedIn touch or phone call to your cadence. Different channels reach people in different contexts, and Yesware (a sales platform vendor) reports that social selling practitioners achieve significantly higher quota attainment than email-only reps.

Why do longer follow-up emails sometimes perform better than short ones?

Gong data shows follow-up emails with more than four sentences can generate more meetings — but Lavender.ai, which analyzes this data, says the reason is context, not length. Prospects forget who you are between touches, so a follow-up that re-establishes who you are and why you're reaching out will outperform a vague 'just checking in' regardless of length. Note this research is based on cold outbound follow-ups and may not translate exactly to warm post-proposal scenarios.

Best Follow-Up Email After Sending a Proposal

You sent the proposal. You sent one follow-up. Silence. Here's what to do next — and why bailing now would be a genuine mistake.

Stop Treating Silence as a "No"

A study by Brevet (cited widely in sales research) found that 80% of sales require at least five follow-ups after the initial contact. Note: this figure is widely circulated as a secondary citation; we recommend verifying directly against Brevet's original research. You're at one follow-up. You're not even close to done.

The problem isn't that your prospect isn't interested — it's that they aren't thinking about you at all. As Lavender.ai puts it: "Prospects don't think about us nearly as much as we think about them." They're not sitting on your proposal weighing pros and cons. They forgot about it the moment the next thing landed in their inbox.

That changes how you should write your next follow-up. It's not a nudge — it's a reintroduction.

What to Actually Say (and How Long to Make It)

Gong published data showing that follow-up sales emails with more than four sentences generated more meetings. Lavender.ai — which works with that data directly — has an important caveat worth understanding: that Gong finding applies specifically to follow-up emails, not cold openers, and the reason longer follow-ups work is context, not length. Keep in mind this research covers cold outbound follow-ups generally, so it may not map perfectly to your post-proposal warm-lead scenario — but the principle holds.

Your prospect needs to know who you are, why you're back in their inbox, and what you want them to do. Lavender's recommended framework:

Context = {Observation} + {Insight / Problem}

Something like: "I sent over the proposal on [date] and wanted to check in. Given what you mentioned about [their specific challenge], I think [specific part of your solution] is especially relevant right now. Worth a 15-minute call this week?"

That's it. Don't just say "checking in." Don't write a novel. Give them context, connect it to their world, make the ask clear.

Timing and Cadence

According to guidance from Smartlead (via a LinkedIn Pulse article on proposal follow-up strategy), here's a cadence that balances persistence with professionalism:

First follow-up: 2–3 days after sending the proposal
Second follow-up: 5–7 days after the first follow-up
Subsequent follow-ups: Space out by 1–2 weeks
Final "break-up" email: After 3–5 follow-ups with no response — leave the door open, but signal you're moving on

Adjust based on signals. If they've opened your emails or clicked anything, tighten the interval. If they've gone completely dark, give them more breathing room between touches.

Go Multi-Channel Before You Give Up

If email alone isn't working after two or three attempts, don't just send another email — change the channel. Yesware (a sales email platform, so take this with appropriate context) recommends incorporating phone calls, voicemails, and social touches like LinkedIn into your follow-up cadence. Their data from 10 million email threads shows the average sales rep sends only two follow-up emails total. That's almost certainly not enough.

Separately, Yesware cites research showing that salespeople who implement social selling achieve 66% greater quota attainment than those who don't — which is a good reason to add a LinkedIn connection request or comment as part of your sequence, not just another email.

A quick LinkedIn message after a third unanswered email isn't desperate — it's smart. Different channels, different contexts, different chances to land when they're actually paying attention.

The Bottom Line

You're not being annoying. You're doing your job. The reps who close deals are the ones who stay in the game long enough for timing to work in their favor. Keep showing up with context and value, not just "just checking in" bumps, and you'll be in far better shape than most of your competition.
