Follow up when they have looked, not before

You send your deck on Monday morning. By Thursday there is no reply. Now you are stuck with a small, annoying question: do you write again, or does that look pushy?

Without any signal, the follow-up is a guess. Some founders write too early and sound anxious. Others wait three weeks and the moment has passed. This post is about replacing the guess with a little information, and about being honest on what that information does and does not tell you.

Why a deck attachment tells you nothing

When you attach a PDF to an email, the file leaves your hands. You do not know if it was opened, forwarded, or sitting unread under forty other messages. You also cannot fix a typo or a stale number after it is sent.

A link works differently. You keep control of what is behind it, and you can see when it is opened. That is the whole idea of individual links in StartupCorners.

One link per person

Your startup page is built from your website in about 2 minutes. You can share it two ways:

• The public link, which you can send to anyone. It is a clean, current page for your startup.
• Individual links, one for each person you send it to. Each one shows you opens, time spent and tabs viewed, plus deck and data-room opens.

It does not show location. Individual links report opens, time spent and which tabs were viewed. That is all.

The one-link-per-person part matters. If you send the same link to ten people, every open looks the same. If you send ten different links, you can tell which conversation moved.

Here is what it looks like in practice.

Sample data

Sent to	Opened	Time spent	Tabs viewed
Harbor Peak Ventures, partner	Yes, twice	A few minutes in total	Overview, Team, Deck
Harbor Peak Ventures, associate	Not yet	None	None

The company in this example is NeuralFlow AI, and the data is made up. Your own table will be different, and it will often be quieter than you hoped. That is normal.

What time spent can tell you

Time spent is the number people most want to over-read. Treat it as a hint, not a verdict.

What it can tell you

• Whether the page was opened at all. This is the most useful fact. No open means the message may not have been seen.
• Roughly how long it stayed open. A few seconds suggests a glance. A few minutes suggests someone spent real time.
• Which tabs they viewed. If someone went straight to the deck and skipped the team, that is a clue about what they care about.
• Whether they came back. A second open on a different day usually means the page was worth returning to.

What it cannot tell you

• Whether they read it. A page can sit open in a background tab while someone is on a call.
• Whether they are interested. Someone can spend ten minutes on a page and still pass. Someone else can spend thirty seconds because they already know your product.
• Why a visit was short. They might be on a phone between meetings. They might have seen enough. You cannot know.
• Who is looking. A link shows activity, not identity.

If you keep those limits in mind, the numbers stay useful. If you forget them, you will invent a story from a single data point.

When a stranger opens your link

Sometimes you check the activity and something looks off. You gave a link to one person, and the opens do not match what you would expect: more of them, at odd times, or a visit long after you sent it.

Most likely, your link was forwarded. A partner showed it to a colleague. A customer passed it to their boss. A friend forwarded it to someone who might help.

This is common, and it is usually fine. Here is how to handle it calmly.

1. Do not guess who it was. The link shows activity, not names. A guess can easily be wrong, and acting on a wrong guess is worse than doing nothing.
2. Do not contact anyone you never wrote to. If you did not send it to them, a cold message because of a link open feels strange.
3. Write to the person you did send it to. Keep it light. Something like: happy to answer questions, and glad to walk anyone on your team through it.
4. Treat it as a soft signal, not a promise. A forward can mean interest. It can also mean someone said, can you look at this and tell me if it is junk.

Nothing here guarantees a reply. It only gives you a reasonable, polite reason to write.

How to time a follow-up

There is no perfect rule, and these are judgments, not laws. They do give you a starting point better than a guess.

The link has not been opened

The message may not have landed. Before you send another, check the basics: the address, the subject line, whether the email was too long. Then send a short, plain note. Do not write did you see my deck. Offer one fresh reason to look, such as a recent milestone.

Opened once, briefly

Give it a day or two. They looked, and they have not decided anything. A quick follow-up too soon can feel like pressure. If you have a real update, send it, and because the page is built from your website, update one field and every link is current.

Opened several times, or several tabs viewed

This is the best moment to write. Ask one specific question or offer a call. For example: would a short call this week be useful, or would you like the data room first. You are replying to interest you can see, without claiming more than you know.

Opened and then silence

One follow-up is reasonable. Repeated pings are not. If you still hear nothing, wait until something real changes, such as a new customer or a shipped feature, and then write once more. Silence after an open is common and does not always mean no.

It is not only for investors

The same habit works wherever you send a page and wait.

• A customer call. Send an individual link before the call. If it has been opened, you can start with, I saw you had a chance to look, what stood out. If not, you can summarize in one sentence and move on.
• An accelerator application. Use a link in the application. When the review window is open, you know whether your page was looked at, and you can keep it current without resubmitting anything.
• A hire. Send a candidate a link to your startup before the interview. You will know if they prepared, and you will not have to wonder if they saw the latest version.

In each case, the point is the same: you act on something you observed, and you stay honest about what it does not prove.

A short checklist before you hit send

• Make one individual link per person.
• Note the date you sent it.
• Check activity before you follow up.
• Read time spent as a hint, not proof.
• If an open looks odd, assume a forward and write only to your original contact.
• Keep follow-ups short, plain and specific.

The next time you send something on Monday, you do not have to wait until Thursday wondering. You can check, think, and then write once, at a sensible time.

StartupCorners is in public beta, free, and English only. Individual links are one part of a page that stays current as your startup changes.
