Hello,
I will help you with your project to pass all mailing authentications like SPF, DKIM, DMARC, RDNS, IP rotation for bulk mailing.
I have more than 5 years of experience in email marketing, installing and configure mailing softwares like Interspire, Mailwizz, Mautic, Mumara, Sendy, Amazon SES and many more.
I would like to have a word with you to make things clear.
Thank You
