Breakup email
You already followed up. They opened it, or they didn't, and the thread is just you. The last email should be a question they can answer without writing a paragraph, including the answer where they tell you to stop.
Copy fills the buttons with this address. It stays in the tab.
Should I close the loop?
Is this a no?
Want me to try again later?
Should this be the last email?
Why one-click answers get more replies
Ignoring you is easy. Writing a kind no is a small chore, so it sits there. A button is smaller than that chore. They click not now, or please stop, and you both get to leave the thread. One-click answers get more replies because you asked for a choice, not a composition.
FAQ
Does the other person need Easy Reply?
No. You install the Chrome extension. They tap a button in the email. The answer comes back to you. That is their whole job.
Will this annoy someone who already ignored me?
A fifth paragraph will. A last question with a stop button will not. You are handing them the exit instead of making them draft one.
What if they never click?
Then you stop. The button did not invent the silence. It gave them one last, very easy way to answer it.
Can I write my own buttons?
Yes. Copy a question and change the words, or set your own question and two to four answers in Gmail. These are starting points for the email where you close the loop.
