LeadIQ is quick and easiest to use with the extension tool paired with LinkedIn Navigator. From there - you're clicks away from uploading contacts into your CRM and preferred cadances. The only reason, its not a 10 because emails are not always accurate (but which contact database is?) but can easily edit them to match with other contacts emails.

The emails I've sourced through LeadIQ have been accurate more times than not (when it has a green check mark). The best part is it's ability to quickly to export into multiple external platofrms and even assign workflows to the leads, all with one click.

Very easy to use, gives a ton of numbers so one of them is often right, has email and phone saved directly to salesforce/outreach
