Hi guys, here is a question about email adversting (invite event) for my old customers (around 20k emails), all of them did play on my previous game server. For now, i'm want to launch a new one, and invite all of them to my new project.
Here is few questions:
1.) How to do it with minimum risk to get NOT banned from VPS operators.
2.) I'm hate spam, and i'm wont to be a spammer.
3.) Any ready solution to do that?
4.) How much it usually costs?
5.) I can configure email server, headers, DKIM, SPF, etc. there is no problem, problem in VPS providers and large email list (20k+)
Can you suggest to me any legal way to do that. Cheaper = better.
