The usual advice – "wait three to five business days" – was written for proposals sent blind. When you can see that the client opened the proposal, went back to the pricing page and passed it to a colleague, the right moment is no longer a guess. This guide gives a timing rule for each signal, a cadence for when there is no signal, and messages that do not sound like surveillance.
Updated 8 November 2026. Disclosure: HelpRange is our product. The timing rules work with any tool that shows when a proposal is opened.
Follow up within a day of a meaningful open – not within minutes – and about the page the client spent time on. If there is no open after 48 hours, check delivery before you chase a decision. Without any signal, the classic 3–5 business days still apply.
| Signal | When to follow up | What to do |
|---|---|---|
| Opened within hours, long time on the pricing page | Next morning (or late the same day) | One concrete question about price or scope – "would a phased start help?" |
| Came back to the proposal two or three times | Within 24 hours | They are comparing or selling it internally: offer a 15-minute call to go through the options |
| New viewers from the client's company | Within 1–2 days | The proposal reached the decision makers: ask who else is involved and offer to present to them |
| Opened, but stopped after the first pages | 1–2 days | Send a three-line summary of the part they did not reach, or ask whether the scope fits |
| Opened once, briefly, then nothing | 3 days | Ask whether it is still a priority this quarter – give them an easy way to say "later" |
| Not opened after 48 hours | Now | Check it arrived: resend the link with one sentence, or call – it may be in spam or with the wrong person |
| Not opened after a week | Now, by phone | A short call beats a fourth e-mail |
An attached PDF cannot tell you anything: once it is on the client's computer, nothing reports back. E-mail open tracking only says the e-mail was opened – and it is often wrong, because mail apps such as Apple Mail with Mail Privacy Protection load images in the background before anyone reads.
What works is sending the proposal as a link instead of an attachment. It opens in an online viewer, and every visit is recorded: who (by e-mail, or by the name you gave the link), when, which pages and for how long, and whether new people joined. Details: how to track PDF opens and proposal tracking in HelpRange.
Never write "I saw you spent four minutes on page 5". Use the signal to choose the topic, not as the message.
In the EU and UK, data about how a known person reads a document is personal data. Say in your e-mail that the proposal is shared through an online viewer that records visits, collect only what you need and keep it no longer than the deal requires. A link that asks for the reader's e-mail makes the tracking visible.
Without any signal, 3–5 business days. If you can see the client opened it, follow up within about a day of a meaningful open – the next morning rather than minutes later – and about the page they spent time on.
Usually that they are comparing offers or presenting yours internally. Offer a short call to go through the options, or to present to the colleagues who joined.
After 48 hours, check delivery before anything else: resend the link with one sentence, or call. After a week without an open, call.
No. Use the signal to choose the timing and the topic of your message; mentioning minutes and pages feels like surveillance.
With a link, yes – a forwarded link shows up as a new viewer, with their e-mail if the link asks for one.
