MailerLite Domain Authentication Setup

I'm looking for a specialist who can assist me with setting up domain authentication for my MailerLite account. This will help to increase my email deliverability and credibility.

Here's what I need:

- Authentication set up via SPF, DKIM, and DMARC (as allowed by MailerLite)
- Testing and verification to ensure the set up is done correctly

Requirements:

- Familiarity with MailerLite
- Experience with setting up SPF, DKIM, and DMARC
- Ability to walk me through the process, so I understand how it's done
