TL;DR
Change your display name in Gmail, then refresh it in lemlist: Settings → Sending settings → Settings next to your sender → Refresh.
Why This Matters
lemlist pulls your sender name directly from Gmail. Keeping this name consistent across tools helps contacts recognize you more easily and can improve reply rates.
