# When to Follow Up After Meeting Someone: A Cadence

> Send the first message within a day or two, come back on the date they gave you, and if they gave none, try once more after a few weeks. And the reasons why.

## Short answer

**Follow up within one to two days of meeting someone, while they can still place you. Then follow up again on the date they gave you (“after the funding closes”, “in November”). If they gave no date and did not reply, try once more after three to four weeks with something new, then leave it until there is a real reason.** The first message proves you listened. The second, on their date, is where most of the value is, and almost nobody sends it.

## The cadence on one line.

Day 0: write the note. Day 1 to 2: first message. Their date: second message. Otherwise three to four weeks, once. After that, only with a real reason.

Each stop on this line has a job. The timeline below is the schedule we recommend and the reason for each stop. It is a method, not a measurement: it carries no reply-rate numbers, because nobody has published honest ones for conversations at UK networking events and we are not going to invent them.

1. Day 0 **Write the note** Who, where, what they need, when, what you promised. Before the next conversation.
2. Day 1–2 **First message** They can still place you. Three sentences and one specific detail.
3. Their date **The one that matters** The moment they named. Almost nobody comes back on it.
4. 3–4 weeks **Once more, if silent** Only with something new. Then stop.
5. Later **Only with a reason** News, an introduction, their date arriving. Never a bump.

A recommended schedule, not measured data. Each stop has a reason under it; none of them has a reply rate, because we do not have an honest one.

The stop marked in blue is the one that decides whether a conversation turns into anything. The first message is manners. The one on their date is useful, and useful is what gets answered.

## Why the first message goes within two days.

Because both of you are forgetting, and forgetting is fastest at the start. After about a week you are reintroducing yourself rather than following up.

The oldest evidence here is also the most honest about its limits. In 1885 Hermann Ebbinghaus memorised lists of nonsense syllables and measured how much he had kept after intervals from twenty minutes to a month. The loss was steepest early and slowed later. His own account is [online in translation, chapter 7](https://psychclassics.yorku.ca/Ebbinghaus/memory7.htm).

Nonsense syllables are not a conversation, and we are not going to put a percentage on how much of yours survives. The direction is what matters, and it matches what everyone recognises: the day after an event you can still hear the conversation; a week later you have a name and a vague sense of the company.

That works on both sides. Within two days, they can still place you, so a short message referencing one specific thing lands as a continuation. After a week it lands as an introduction, which is a harder message to write and an easier one to ignore.

## The date they named beats any rule.

If they told you when to come back, that date overrides everything else on this page. Write it down as a date, and be the one who remembers it.

“Come back to me after Christmas.” “We are reviewing suppliers in November.” “Once the new hire starts.” People say these things at events all the time, and they mean them. By the time the date arrives they have forgotten saying it to anyone.

That is the whole opportunity. The person who comes back on the date is not following up; they are keeping a promise the other person has forgotten they were owed. It costs one line in a calendar, as long as the line is written as a date on the day. “Next Tuesday” in a note is useless in three weeks.

A date written as a date. The real contacts page on a demo account, 22 September 2026: the note said “next Tuesday”, and the row now says Tue 29 Sep.

This is how Cardr keeps it: the date comes from the words in your note, and it sits on the contact where you will see it. On [Pro](https://cardr.co/pricing) you are also emailed on that day with the message already drafted. We cover what to capture in [how to remember people you meet](https://cardr.co/blog/how-to-remember-people-you-meet-at-networking-events).

## If they do not reply.

Send one more message after three to four weeks, and make it carry something new. Then stop until there is a genuine reason, such as the date they gave you.

Silence after a first follow-up usually means busy, not no. It does not mean they want a “just bumping this” a week later, which asks them to do the work of remembering you.

- **Wait long enough to have something new.** An article that fits the problem they described, an introduction, a relevant bit of news about their sector. Three to four weeks usually gives you one.
- **Make it answerable in a sentence.** Or make no ask at all.
- **Then stop.** Two unanswered messages is the line. A third turns you into the thing they are ignoring.
- **Except on their date.** If they named a moment, that is a legitimate reason to write whatever happened before.

## Timing in a UK week.

Send when they will read it: a working morning, not a Friday afternoon or a bank holiday. Watch August and the second half of December, when many people are away.

These are judgement calls rather than research, and we would rather say so than dress them up.

- **A working morning.** A message that arrives while someone is at their desk is dealt with; one that arrives at 9pm on a Friday is buried by Monday.
- **Check the bank holidays.** England and Wales, Scotland and Northern Ireland have different ones. [GOV.UK lists them](https://www.gov.uk/bank-holidays). A first follow-up that lands on a bank holiday Monday is a first follow-up that lands on Tuesday under everything else.
- **Mind August and late December.** If the event was in the last fortnight before Christmas, a short thank-you now and the real follow-up in the first full week of January is often better than one message that gets lost.
- **Match the channel to how you met.** If they gave you their mobile and said to message, a WhatsApp is fine. If they gave you a business email, use it.

## Where Cardr fits in the cadence.

Cardr keeps the date against the contact for free. On Pro it emails you on that day, or three days after you met if you gave no date, with a follow-up drafted from your note.

Being straight about what it does and does not do:

- **Free:** the exchange that returns their details to you, the note, the date worked out from your words, and a contacts list you can search and export.
- **Pro, £12 a month or £9 billed annually (£108 a year):** a reminder email on the date you said, or three days after you met if you gave no date, sent at 9am your time; and AI-drafted follow-ups from what you wrote, for 200 people a month.
- **Not built:** sending anything on your behalf. Cardr drafts; you read it and press send. We think that is right for a message that has your name on it.

## Questions, answered

### How soon should you follow up after meeting someone?

Within one to two days, while they can still place you. After about a week you are reintroducing yourself rather than following up.

### Is it too late to follow up after two weeks?

No, but change the message. Acknowledge the gap briefly, lead with the specific thing they told you, and give them a reason to reply now. If they named a date that has not arrived, wait for it instead.

### How many times should I follow up if there is no reply?

Twice in total, then stop: the first message within two days, and one more after three to four weeks that carries something new. The exception is a date they named themselves, which is always a legitimate reason to write.

### What day of the week is best to send a follow-up?

A working morning when they are likely at their desk. We do not have trustworthy data on specific days for UK networking follow-ups, so we recommend avoiding the obvious bad times, Friday evening and bank holidays, rather than chasing a magic day.

### Should I follow up the same day?

The same evening is fine for a short message if the conversation was clearly going somewhere. The next morning is usually better: it reads as considered rather than automatic, and you have had time to add the one specific detail.
