I need both GoDaddy SMTP and Postmark SMTP fully set up so my custom-built application can send high-volume marketing campaigns without hitting spam filters. The domains are already registered and hosted with GoDaddy; nothing beyond basic DNS has been touched. Here’s what has to happen: • Activate and authenticate each SMTP service, adding and verifying all SPF, DKIM, and (where applicable) DMARC records in the GoDaddy DNS zone. • Supply the final hostnames, ports, and credential strings my developers can drop straight into our app’s mailer module. • Run test sends from the app’s staging and production environments, confirm inbox placement (Gmail, Outlook, Yahoo), and share the headers/screenshots as proof. • Document exactly what you changed, including rollback notes, so future migrations are painless. If you have recent experience with GoDaddy’s dashboard quirks and Postmark’s API tokens, this should be straightforward. I’m ready to give you immediate access to the DNS panel and the Postmark account as soon as we agree on the timeline.
