The Banana Opt-Out Line Pack: 12 Reply-to-Stop Lines for Cold Email

Why some cold emailers swap the link for a line

One cold email agency shared this idea: they took the unsubscribe link out of their cold emails and put one plain line at the bottom instead: "If you don't want more emails, reply banana and I'll stop."

Their reasoning: a click on an unsubscribe link is a silent goodbye. A "banana" comes back as a reply. You see it, you stop, and the person feels heard. They also believe replies count as good engagement with spam filters. That last part is their view, not a published Google rule, so don't treat it as a guarantee.

The funny word does one more job: it makes saying no feel easy and friendly. People who are annoyed can leave without hitting the spam button.

What the rules actually say (read this first)

The banana line is an opt-out method, not a way around the rules. You still have to make it clear, and you still have to honor it fast. Here is what the official sources say.

One more US rule people forget: the FTC guide also says commercial emails must include your valid physical postal address. Keep it in your signature, even if you remove the link.

When to use the line, and when to keep the link

The 12 lines (copy and paste)

Pick one and use it at the very bottom, under your name. Keep it in normal-size text. A line hidden in tiny grey font is not "clear".

PLAYFUL
1. If you don't want more emails, reply "banana" and I'll stop.
2. Not for you? Reply "pineapple" and you won't hear from me again.
3. Wrong person or wrong time? Reply "taco" and I'll stop here.

PLAIN
4. Not interested? Reply "stop" and I won't email again.
5. If this isn't useful, just reply "no thanks" and I'll take you off my list.
6. Reply "remove" and I'll stop emailing you today.

POLITE
7. If you'd rather not get emails like this, let me know and I'll stop right away.
8. No reply needed if it's a no. But if you want me to stop, reply "stop" and that's it.
9. Happy to leave you alone. Reply "pass" and you won't hear from me again.

WITH A REFERRAL ASK
10. Not you? Reply with the right person's name, or "banana" if I should stop.
11. If someone else handles this, I'd love a name. If not, reply "banana" and I'm gone.
12. Wrong fit? Reply "banana" to stop, or "later" and I'll check back next quarter.

How to set it up

1. Add the line to every cold email in the sequence, not just email 1. Every email needs a way out.
2. Check replies go somewhere you read. Send a test, reply "banana", and make sure it lands in your inbox or your sending tool's reply view.
3. Make an "Opt-out" label in your sending tool or inbox. Tag every banana, stop, remove or "not interested" reply with it.
4. Add them to your block list (sometimes called a do-not-contact or suppression list), so no future campaign can email them. Removing them from one campaign is not enough.
5. Stop all sequences for that person today. Aim for the same day. Use 2 days as your hard limit, to match Yahoo and Google's guidance.
6. Don't sell in any reply. You don't need to answer. If you do, keep it to one line, like "Done, you won't hear from me again."
7. Keep the list forever. Export it every month and import it into any new tool or new campaign.

Treat every "no" like a banana

Most people won't use your word. "Please stop", "take me off", "not interested", "who gave you my email?" and rude replies all mean the same thing. Any clear request to stop is an opt-out, whatever words they use.

Worked example: how much work is this?

Example numbers to show the size of the job (use your own):

1. You send 300 cold emails a day, 5 days a week = 1,500 emails a week.
2. Say 1% of them reply asking to stop: 1,500 x 1% = 15 opt-outs a week, about 3 a day.
3. Tagging and blocking each one takes about a minute = about 15 minutes a week.
4. Miss them for two weeks and you've broken the US 10-business-day rule for every one of them. Fifteen minutes a week is cheap protection.

Common mistakes

Sort your replies with Claude

If you get a lot of replies, paste them into Claude once a day and let it sort them. Check its work, and when in doubt, treat it as an opt-out.

Here are today's replies to my cold emails. Each one has the sender's email and the text:
[paste replies]

Sort every reply into ONE of these groups:
- OPT-OUT: any request to stop, be removed, "banana", "not interested", angry or rude replies
- INTERESTED: wants to know more or talk
- NOT NOW: interested later, give the date if they said one
- WRONG PERSON: gave another name or said it's not their job
- OUT OF OFFICE / AUTO-REPLY

Rules: if you're not sure between OPT-OUT and anything else, choose OPT-OUT.
Return a table: email, group, one-line reason. Then list all OPT-OUT emails on their own, one per line, so I can paste them into my block list.

Daily checklist

• Every cold email has a clear opt-out line in normal text.
• Your postal address is in the signature.
• All opt-out replies from today are tagged.
• All of them are on the account-wide block list.
• None of them are still in an active sequence.
• Newsletters still use a real unsubscribe link.

Quick answers

Is it legal to remove the unsubscribe link from cold email?

In the US, CAN-SPAM asks for a clear way to opt out, and a reply email can be that way. But you must honor it within 10 business days and include your postal address. Bulk senders to Gmail and Yahoo need one-click unsubscribe for marketing mail, and UK and EU rules are stricter. This is not legal advice, so check your local rules.

What if they reply "stop" instead of "banana"?

Treat it exactly the same. Any clear request to stop is an opt-out, whatever words they use.

Do banana replies really help my deliverability?

Nobody outside Google or Microsoft can prove that. What is clear: an easy, friendly way to say no gives annoyed people an option other than the spam button.

Can I use the banana line on my newsletter?

No. Newsletters and marketing lists should keep a real unsubscribe link and the one-click header. Use the line for one-to-one cold email.
