TWO TIP: Best Opt-In Words

Call to action copy for opt-in e-mail should consider not using terms like “Subscribe to,” or “Register for.” Some readers will infer that there’s a financial obligation due or a fee for service.

“Sign up for” copy is better because it’s friendly without suggesting a commitment.

“Join” makes prospects feel that they are part of a group entitled to special benefits. “Exclusive Offer” subject lines should appeal to these people too.
