Subject: Approval delays after [trigger event]
Hi Sam,
I tried you just now. I work with finance leads on approval delays when a team grows. Is this something you handle?
If not, who should I ask?
Alex
After a conversation
Subject: Thanks, Sam
Hi Sam,
Thanks for the time today. You said approvals take about three days. I will send two examples of how teams cut that. Does Thursday morning suit for a 20-minute call?

Meeting booked
Subject: Thursday 10:00, approval delays
Hi Sam,
Confirming Thursday at 10:00 for 20 minutes. I will cover your current approval steps and where they slow down. Please bring one recent example if you can.
Calendar invite attached.

Rules for all three
- Subject line names the topic, not your company.
- Start with the buyer, not with yourself.
- End with one question or one fact.
- Say what you will cover and for how long.
Where it fits
Send the first template with a voicemail when nobody answers. The outreach cadence templates show the next touches in a sequence. For what to say on the call itself, see the cold call script.
Next step: score the calls behind your follow-ups with the free SDR call scorecard.
Questions
When should an SDR send a follow-up email?
Within minutes of the call. A short note the same day beats a longer one the next week.
How long should the email be?
Under 60 words. The buyer reads it on a phone.
Should I attach anything?
Attach a calendar invite for a booked meeting. For other emails, send nothing until the buyer replies.
