Nine emails for the moments that actually work: after delivery, after a result, after a thank-you, plus the two follow-ups where most testimonials arrive. Swap the placeholders and send.
Send within 48 hours of handing over the work, while the relief is fresh.
Subject: Quick favour, 2 minutes?
Hi {{first_name}},
Now that {{deliverable}} is live, would you mind answering two questions about it?
1. What was the situation before we started?
2. What changed since, in numbers if you have them?
Here's a link that takes about two minutes, you can type or record a voice note: {{link}}
No pressure if now is a bad week.

After a measurable result
The strongest moment. A number just landed, so ask while it is on their screen.
Subject: That {{metric}} number
Hi {{first_name}},
Saw the {{metric}} figure come in. That's a real result and I'd love to write it up properly.
Would you answer three quick questions so I can quote you accurately rather than paraphrase? {{link}}
You'll see and approve the final version before it goes anywhere public.

After an unprompted thank-you
They already wrote the testimonial, they just sent it to the wrong place.
Subject: Can I quote you on that?
Hi {{first_name}},
Thank you for the kind message the other day, it made my week.
Would you be comfortable if I used part of it publicly? If you'd rather add a line or two of context, here's the link: {{link}}
Either way, nothing gets published without your approval.

4
End of a retainer or project
Offboarding email. Put the link next to the final handover.
Subject: Wrapping up {{project}}
Hi {{first_name}},
Everything is handed over, files are in {{location}}.
One last thing: I'm putting together a short write-up of the project. Would you answer a few questions about the before and after? {{link}}
It helps the next client understand what this kind of work actually does.

5
Long-term client, no obvious trigger
For people you have worked with for months and never asked.
Subject: Overdue question
Hi {{first_name}},
We've been working together for {{duration}} now and I've never once asked you for a testimonial. Fixing that.
Four questions, two minutes, text or voice: {{link}}
Answer only the ones you feel like answering.

Follow-up 1, gentle nudge
Five to seven days after the first email. Most testimonials arrive after this one.
Subject: Re: Quick favour, 2 minutes?
Hi {{first_name}},
Bumping this in case it got buried. Same link: {{link}}
If it's easier, reply to this email with a couple of sentences and I'll take it from there.

Follow-up 2, make it one question
Ten days later. Drop the form, ask for one line.
Subject: One question instead
Hi {{first_name}},
Last time I'll mention this, promise.
Forget the form. Just reply to this email with one sentence: what changed after we worked together?
That's enough for me to work with.

8
Video testimonial ask
Only for your happiest clients. Higher friction, much higher impact.
Subject: Would you record 60 seconds?
Hi {{first_name}},
Bit of a bigger ask: would you record a 60-second video about the {{project}} work?
No script needed, the link shows the questions on screen while you record, and you can retake as many times as you like: {{link}}
Phone camera is perfectly fine. If video isn't your thing, a voice note works too.

Permanent link in your signature
Not an email, a line at the bottom of every email you send.
Subject: (email signature)
{{your_name}}
{{your_role}}
Worked together? Leave 2 minutes of feedback: {{link}}
Six rules that decide whether they reply
Name the moment
Generic asks get ignored. Reference the exact project, launch or number so it reads as personal, not as a mail merge.
Say how long it takes
'Two minutes' removes the biggest silent objection. If you say it, keep it true, four to six questions maximum.
Offer a way out
'No pressure if now is a bad week' raises reply rates. It removes the awkwardness of saying no to a client relationship you value.
Promise approval
Tell them nothing gets published until they approve it. That single line converts the cautious ones.
Always follow up twice
Most testimonials arrive on the second or third email. The first one lands in a busy inbox, not in a hostile one.
Let them speak, not type
Give a voice note option. Spoken answers are longer, more specific and sound like the client rather than like a template.
Common questions
The link these emails point to
One collection link asks the questions, records text or voice, stores the consent, and turns the answer into a case study and an X thread you can publish.
