How to organize mailing of registration for an event?

Question

Email

Good day to all!
Can you please tell me how it is possible to organize email-mailing (addresses are completely white)?
You need to send out an invitation to the event with the possibility of registration.
I looked in the direction of sendpuls, but they insert their own text (sent via sendpuls (or something like that)), and I don’t really want to see such a record.
Perhaps it is possible to somehow organize a mailing list through the site (on WP), and if so, if I understand correctly, then you need to create a registration page on the site? Or install a plugin.
Perhaps you know a resource where it is described in detail how this is done? Or can you share your experience?
Zero understanding so far.
I would very much like to look into this matter.
Thank you.

If time allows, then rummage around on the Stripo website. This is a letter constructor, but they give a lot of advice on working with mailers on their blog and in articles.

If organized through a mailing service, sendpulse, unisender, esputnik, etc., on free plans everywhere there will be a signature through which service it was sent. Through a website builder like Tilda, you can immediately collect addresses through a form and send emails. An example of how to register for a webinar through a mailing service
