Automating client follow-ups without a costly CRM

Three building blocks are enough to automate your follow-ups: a form that records every request, an email sending service, and a clock that checks every hour who needs a follow-up. The basic sequence fits in five messages: an instant acknowledgement, a follow-up at day 2 then day 7, two quote reminders, and a review request after delivery.

Why requests get lost

Requests arrive through the website, by email, on Instagram and by phone. Each one needs a reply, then a follow-up if the person goes quiet. Without a reminder, you follow up when you think of it, which means too late or never.

A prospect who does not reply has not necessarily said no: they were often busy with something else. A short follow-up at the right time is enough to restart the conversation. That is exactly what an automation does, without forgetting anyone.

The 5-message sequence

  • 01On request: a personalised acknowledgement that restates the need and gives a reply time.
  • 02Day 2, no meeting booked: a short follow-up, one question ("any question about your project?") and one simple action, reply with two time slots.
  • 03Day 7: a concrete example (a project, a page about their sector), then the request moves to a monthly follow-up.
  • 04Quote sent: a reminder at day 3, another at day 10, and at day 21 a message that closes the file and asks, in one line, what got in the way.
  • 05Project delivered: at day 7, a request for a review and a testimonial; later, a maintenance offer and a referral request.

The three building blocks

  • 01A database: the list of requests with their status (new, call booked, quote sent, won, lost). A Google Sheets spreadsheet is enough to start; a database takes over as volume grows.
  • 02A sending service: Brevo, for instance, sends emails from your own address, with an unsubscribe link. Its free plan allows 300 emails a day at the time of writing.
  • 03A clock: Google Apps Script (free with a Google account), n8n or Make. Every hour, it checks which requests need a follow-up and triggers the email.

Rules that avoid spam and annoyance

  • 01A follow-up stops as soon as the person replies or the status changes: nothing is worse than an automatic reminder after a call.
  • 02Every email includes an unsubscribe link, and unsubscribing is honoured immediately.
  • 03Your domain is authenticated (SPF, DKIM, DMARC) before the first send; otherwise your messages land in spam.
  • 04Emails go out on working days, in daytime, as if you were writing them yourself.
  • 05Each step has a window: a request caught up late never receives three messages at once.

What to write in a follow-up

  • 01The context in one sentence: the request or quote concerned.
  • 02A single question, easy to answer.
  • 03A single action: reply to the email, with time slots if needed.
  • 04A signature with your name: a follow-up reads better when it comes from a person.
  • 05No pressure: the last message leaves the door open.

Doing it yourself, or getting help

With a spreadsheet, Brevo and a few dozen lines of Google Apps Script, an organisation comfortable with these tools can build this sequence itself. It is the system running on ylnstudio.com: every request gets an acknowledgement, then follow-ups at day 2 and day 7 as long as nothing has moved.

If you would rather hand it over, YLN Studio's System stage sets up a CRM connected to your forms, automated emails (confirmation, follow-up, reminder) and online booking, from €2,400 excl. VAT, delivered in 3–4 weeks. The free 45-minute diagnostic shows what makes you lose requests today.

FAQ

Do you need a CRM to automate follow-ups?

+

No. A spreadsheet, an email sending service and a clock such as Google Apps Script are enough to start. A CRM becomes useful when several people handle requests or when volume grows.

How many follow-ups should you send?

+

Two follow-ups after a request (day 2 and day 7) and two after a quote (day 3 and day 10), then a closing message. Beyond that, you annoy more than you convince.

Are automated follow-ups legal?

+

Yes, if the person contacted you and agreed to be contacted back, and if every email lets them unsubscribe. In B2B, the French data protection authority (CNIL) also allows email prospecting when the message relates to the recipient's professional activity and offers an unsubscribe link.

Will my follow-ups end up in spam?

+

Not if your domain is authenticated (SPF, DKIM, DMARC), the messages are short and personal, and you send from your own address rather than a generic one.
