Hey there,
After reviewing your project description its clear that you want someone to setup a SMTP server for you so that you can send 1300 email twice a month. Currently you can't send much emails because your list is not opted in.
I'm very experienced with System Administration, Network Administration, SMTP Server Configuration and Troubleshooting, SMTP Authentication(SPF, Dkim, Dmarc, rDNS), SMTP IP/Domain Reputation.
I'll be happy to do this project for you.
Thanks in advance for giving the opportunity to working with you.
Have a good day.
Best Regards,
Serazum Munir.
