Best practices for confirmation emails

Lead the body copy with explicit confirmation language so users feel their action registered successfully and immediately.
Display subscription tier, billing cycle, or plan name visibly so users self-validate the correct option was selected.
Use a single primary CTA button that advances onboarding rather than pointing back to a generic homepage.
Include a brief what-to-expect section outlining the next two or three steps to reduce post-signup anxiety and drop-off.
Add a low-friction secondary link for account settings or support so confused users never need to search for help.
