Too Long; Didn't Read
As a growth hacker I do cold emailing. A lot of companies rely on this lead source for marketing campaigns. Some people think that GDPR does not allow cold emails. But, no, they are wrong. Cold emails is direct marketing. You can do cold emails for your business if you do it right. You cannot write cold emails to individuals (B2C) without their implicit consent. You should always introduce yourself — both your full name and the company you represent. You should use only email addresses available in public lists.
