Adding Recipients
You should only email individuals who have explicitly opted in and expect to hear from you. Always use a confirmed (double) opt-in process:
Send a single confirmation email and require the recipient to click a link in that message to verify their subscription.
This extra step ensures the address is valid, prevents accidental or fraudulent sign-ups, and helps you maintain a high-quality, engaged list — reducing complaints and improving deliverability.
