Mailing List Help? (50subs!)

Hi IndieHackers.

I have a sub form on my site but I don't know much about running a mailing list and sharing updates with users.

When it was one or two subscribers I was using a free outlook account for comms but now its a big list everytime I send a mass email out my account gets blocked (I didn't realise it was against personal account service agreements).

I think the following is what I need to properly support contact emails - please correct me if I'm wrong on this before I go ahead and make mistakes because it's quite daunting!:

• free email address from current hosting provider
• p/o box to add to my mailing list info
• ?a mailing list plugin solution to manage bulk and scheduling emails? What do you guys use and do I need a paid option?

Thanks!
