If your emails are landing in spam folders — or worse, someone is sending emails pretending to be you — it is time to set up email authentication. SPF, DKIM, and DMARC are three DNS records that tell receiving mail servers your messages are legitimate. This guide walks you through setting up all three on your HOSTDOG hosting.

This guide walks you through adding your HOSTDOG email to the Gmail app on Android, step by step. We use IMAP, which keeps your emails in sync across all your devices. These instructions work on all Android phones and tablets running Android 10 or later.

Every time you open your email client — whether it's Outlook, Thunderbird, or the Mail app on your phone — it connects to the mail server using either IMAP or POP3. Both protocols do the same basic job (fetching your messages), but they work in fundamentally different ways. Understanding these differences helps you pick the right setup for your workflow.
