Before buying another lead list, check the prospects you couldn't email.
Your list may already include people who fit your offer, with a relevant buying signal giving you a reason to reach out. If your sequence requires a verified email, those contacts can get left out.
If you stop there, you've let a missing address overrule the buying signal.
That's the blind spot in single-channel outbound. A prospect can fit your offer and still be unreachable through the only channel you've set up.
Try another data source first. If you still can't find a verified email, check whether LinkedIn gives you a sensible way to reach them. If it does, route them into LinkedIn outreach and check the connection before messaging.
That's why we've prioritised email and LinkedIn outreach in Overloop AI. You can keep both in the same campaign and choose the next step based on the contact details available for each prospect.
LinkedIn is worth prioritising for high-value prospects too, even when you have their email.
If they're active there, you can use the buying signal to start a relevant conversation. Since LinkedIn has its own limits, be deliberate about which prospects get that attention, and stop the sequence when they reply.
