Collected a lot of mailbox information about cryptocurrency. It's about 100K.
But I don't know much about email marketing.
I hope GUYS can give good suggestions.
How to be effective without being treated as spam.
If you are looking for a good guide in email marketing there are lots of good tutorials on youtube, and it's very easy to learn this you just need time to see the basics, If you want to start now on email marketing you can try MailChimp they have 2000 mail for free subscription per month to get you started. I have tried this platform and its very good in my experience you can see your mail if it's opened, click or not and also you will see people who will unsubscribe in your mailing list. You will only be
spam if you don't put a receiving mail on MailChimp so it's better to ready you're receiving email (
this mail is for people who want to contact you) I hope this will help you to get you started on your journey to be a great email marketing 😉
