PersistIQ gives you the sales automation platform and outbound sales team to help small businesses set up their own outbound sales engine to get new clients.
If your budget is tight we'd recommend this tool. It's relatively cheap and still does the core job of email automation. Although we wouldn't recommend running large volumes through it. They also have a decent "email finder" Chrome extension.
FindThatLead is an all-in-one B2B data provider and email outreach tool. They also have a Chrome extension that allows you to quickly find and verify emails from any website or LinkedIn profile.
This is a well-priced tool that's worth a try! The interface is simple yet a pleasure to use. It comes with an email finder and bulk email verification tool, in addition to email outreach and tracking.
