The one email where the reader knows nothing about you yet. Every line below is scored against the same welcome profile the tester below uses: short, warm, no manufactured urgency.
27.9% average open across 17,427 OnVoard welcome sends.
Aggregate across every OnVoard merchant running a Welcome Series, not a single store, and it moves with list quality: the same snapshot shows a 2.7% hard-bounce rate on welcome sends, higher than any other flow we measured, which points at new-subscriber list hygiene more than at the subject line.
First impression, and the only email where the reader knows nothing yet. Be warm, be short, and say what happens next. Every line below is scored against this exact profile in the subject line tester.
Grouped by purpose. Every line scores 85 or higher against the welcome profile, with no red checks. Click "Test this" to see why, or to try your own version of it.
These are the subject lines. OnVoard runs the Welcome Series workflow itself, from the first email to the last, so it goes out automatically when someone joins your list.
