Follow Up Reminder Email: When to Send It and What to Say

A follow up reminder email is a short, professional message sent after no response to an earlier communication. The goal is to move a stalled thread forward — not to pressure, but to make it easy for the other person to reply. Done right, a follow up email is a service, not an annoyance.

Here's exactly when to send them, what to say, and how to make sure you never forget to follow up in the first place.

When to Send a Follow Up Reminder Email

Timing matters more than most people think. Send too soon and you look impatient; wait too long and the opportunity evaporates.

General timing rules by context:

Situation	First Follow Up	Second Follow Up
Job application	5–7 business days	5–7 days later
Business proposal	5–7 business days	7–10 days later
Invoice unpaid	3 days after due date	7 days later
Meeting recap or action items	24 hours	48–72 hours
Sales outreach (cold)	3–4 days	4–5 days later
Colleague internal request	3 business days	2–3 days later

For time-sensitive threads — contracts, client sign-offs, legal documents — 24–48 hours is appropriate. Always reference the specific deadline when you do.

Follow Up Email Subject Line Formulas

The subject line determines whether your email gets opened. Three formulas that work:

1. Reply thread: Re: [Original Subject] — highest open rates because it looks like a continuation
2. Name + action: [Name], following up on the Q2 budget review
3. Deadline anchor: Contract expires Friday — quick follow up

Avoid: generic subjects like "Checking in" or "Following up" with no context. They get buried or filtered.

Copy-Paste Follow Up Reminder Email Templates

Template 1: Gentle first follow up (general)

Subject: Re: [Original Subject]

Hi [Name],

Wanted to follow up on my message from [day]. Do you have a few minutes this week to connect, or is there anything you need from my end to move forward?

Best, [Your name]

Template 2: Unpaid invoice reminder

Subject: Invoice #[number] — payment follow up

Hi [Name],

This is a friendly reminder that Invoice #[number] for $[amount] was due on [date]. If you've already sent payment, please disregard. Otherwise, you can pay here: [link].

Let me know if you have any questions.

Template 3: Awaiting decision or approval

Subject: Re: [Project/Proposal name] — still need your go-ahead

Hi [Name],

I wanted to check in on [proposal/contract/request] sent on [date]. The team is ready to move once we have your sign-off. Is there anything I can clarify?

Deadline: [date] — after that we'll need to [consequence, e.g., push to next quarter].

Template 4: Job application follow up

Subject: Following up — [Position title] application

Hi [Name],

I submitted my application for [role] on [date] and remain very interested in the position. I'd welcome any update you can share on the timeline.

I'm happy to provide any additional materials.

Never Miss a Follow Up: Set a Reminder When You Send

The biggest reason follow ups don't happen: people forget. They send the original email, get busy, and remember three weeks later.

Fix this by setting a follow up reminder the moment you hit send. You can use YouGot — just text or type a natural-language instruction and get reminded via SMS, WhatsApp, or email:

• Remind me to follow up with James about the Q3 proposal if no reply by Thursday at 2pm.
• Send me a reminder Friday morning to check if the Miller contract has been signed.
• Remind me to follow up on my job application to Acme Corp next Monday at 9am.
• Text me in 5 days if I haven't heard back from the design agency about the logo project.

No calendar event needed. No task-app setup. Just a plain-English reminder that fires at the right time.

How to Follow Up Without Being Annoying

Professional follow ups get results. Desperate ones get ignored — or worse, damage relationships. Here's how to stay on the right side of the line:

Do:

• Reference the original message specifically (date, topic, what you need)
• State the deadline or consequence clearly if one exists
• Make it easy to respond with a single yes/no or link
• Add value when possible (updated info, alternative options)
• Give the person an easy out: "Happy to reschedule if this week is bad"

Don't:

• Apologize for following up ("Sorry to bother you...") — it undermines you
• Send three follow ups in three days
• Use guilt or passive-aggressive framing ("I've been waiting for two weeks...")
• CC their boss without explicit reason
• Use vague subject lines

When to Stop Following Up

After three unanswered follow ups over 2–3 weeks, send a final closing email:

Hi [Name],

I've reached out a few times about [topic] without a response, so I'll assume the timing isn't right. I'll close the loop on my end — feel free to reach back out whenever works for you.

This is professional, respectful, and occasionally prompts a response from people who've been meaning to reply. After that, move on.

For sales contexts, YouGot for sales teams helps schedule automated multi-touch follow up sequences without manual tracking.

Frequently Asked Questions

When should I send a follow up reminder email?

Send your first follow up 3–5 business days after the initial message if no reply. For time-sensitive items, 24–48 hours is acceptable. For proposals or contracts, wait 5–7 days. Most recipients need 2–3 touches before responding — persistence is fine if your message is concise and relevant.

How do you politely write a follow up reminder email?

Keep it under 100 words. Reference your original message briefly, state what you need and by when, and include one clear call to action. End with a soft out like 'Happy to reschedule if timing is off.' Avoid apologizing for following up — you're doing your job.

What is a good subject line for a follow up reminder email?

The best subject lines reference the original thread: 'Re: [original subject]' has the highest open rate. If starting fresh: 'Quick follow up — [topic]' or '[Name], still need your sign-off on X' work well. Avoid vague subjects like 'Following up' with no context.

How many times should you follow up before giving up?

Three follow ups over 2–3 weeks is a reasonable professional limit. After three unanswered messages, send a final 'closing the loop' email and move on. Sales follow ups can be more persistent — 5–7 touches is normal in that context.

Can I automate follow up reminder emails?

Yes. Email tools like Gmail Sequences or CRMs handle scheduled follow up emails. For personal reminders to follow up manually, YouGot lets you type a plain-English instruction — 'Remind me to follow up with Sarah on Thursday at 9am' — delivered via SMS or email with no app setup required.
