4. Use Double Opt-In Confirmation
An often-overlooked yet highly effective expert tip to improve your email and SMS databases is to implement double opt-in confirmation. This means after someone signs up, they receive a follow-up message (email or SMS) asking them to confirm their subscription. This extra step may slightly reduce your sign-up rate, but it significantly improves the quality of your contacts.

Double opt-in filters out bots, fake sign-ups, and typos. It ensures that the users who enter your database are genuinely interested in your offerings, leading to higher engagement and lower unsubscribe rates.

5. Offer Valuable Incentives for Sign-Ups
If you want people to willingly join your email and SMS lists, give them a reason to do so. Incentives such as discounts, free trials, downloadable content, or exclusive access to information can make the difference between a pass and a successful opt-in.

Make sure your value proposition is clear. Explain what kind of messages they will receive, how often, and how it benefits them. Transparency builds trust, and trust builds a better database.
