I’ve a multisite network with 3500+ sites. I would love to be more engaged with my users and send them newsletters. But I’m affraid of the numbers. Here are my questions:
– Can I just activate e-newsletter and send-out a newsletter to all my members?
– Will this influence my performance?
– Doesn’t this blacklist my SMTP server?
– Are there any other tips and tricks I should think of?
Thanks in advance,
