Post-Purchase Email Subject Lines

They already paid. This one is service, not selling. Every line below stays in that lane.

50.7% average open across 79,387 OnVoard post-purchase sends.

Aggregate across all OnVoard merchants. Post-Purchase flow delivery ran 76.0% in this snapshot, below our blended average, mostly from suppression (skips), which is often working as intended rather than a deliverability problem, but worth knowing before you cite the figure.

What works

Order status, care instructions, and what-happens-next framing all read as service. The profile wants 25 to 48 characters and 4 to 8 words, room enough for a full sentence.
Practical, specific detail beats a generic thank-you in this profile: "how to wash your new linen shirt" scores higher than a plain "thanks for your order" because it tells the reader something they can use.
No urgency at all is correct here (the profile is "off"). Nothing about a shipped order is time sensitive in the reader's inbox.

What to avoid

Selling in the subject line. The reader just paid you; a promotional pitch this soon spends the goodwill the campaign guide (and the scorer's spam check) is built to protect.
Any manufactured urgency. There is no deadline on a package that already shipped, and pretending otherwise costs trust on the next email you send.
Shouting or stacked punctuation on good news. "Your order shipped!!" reads as a promotion, not a status update.

They have already paid. This one is service, not selling. Selling in the subject line spends the goodwill. Every line below is scored against this exact profile in the subject line tester.
