SmartReach.io is a Email Outreach Software designed to let users schedule and send personalised emails and follow-ups automatically from their mailbox and boost their reply rates.
It's straightforward, only has what you need and does not over complicate things. We use it for our own outreach so can definitely vouch for it!
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.
