Set Up Email Authentication Records (SPF/DKIM/DMARC) Across 3 Domains

Job Description: I need a DNS / email deliverability specialist to properly configure email authentication records for 3 domains. All three domains are running on Spacemail (Spaceship.com). Scope of Work: - Retrieve the unique Spacemail DKIM keys from the "Inactive Records" section of the Spaceship dashboard. - Set up standard Spacemail SPF records (or merge them if existing entries exist). - Configure a safe, baseline DMARC record (p=none) for all 3 domains to monitor initial traffic. - Verify successful propagation and alignment using tools like MXToolbox. Requirements: - Proven experience with DNS management and email authentication. - Familiarity with Spaceship / Spacemail or similar modern domain platforms. Turnaround: Looking to get this completed within the next 48 hours. Please mention your experience with Spacemail or standard DNS setups in your proposal.
