Hello,
I can configure an email server along with the Mailwizz application and PowerMTA in the back end for bulk mailing with all mailing authentications like SPF, DKIM, DMARC, RDNS, IP rotation, etc.
So you can send the bulk emails on your email list.
I have more than 5 years of experience in bulk mailing, email marketing, SMTP'S Power MTA, Interspire, Sendgrid, Mailwizz, Mautic, Mumara, Sendy, AWS SES, and mailing application with secured server set up.
You can simply open the application on the browser and start bulk mailing.
Thank You
Raviraj
