Editing Subdomains and deliverability (section)

== Common Use Cases with Examples ==
Utilizing subdomains effectively can significantly enhance your email marketing strategy. Here are some typical use cases:

- **Transactional Emails**: 
  - Examples include '''order confirmations''', '''password resets''', and '''delivery notifications'''. These emails usually yield the highest engagement rates and the lowest spam complaint rates.
  - Consider using integrations like the '''Postmark CX App''' within ActiveCampaign to facilitate these transactional emails from your automations.

- **Batch Sends**: 
  - Newsletters, promotions, new product announcements, and brand updates are often sent as batch emails.
  - It is essential to monitor engagement levels as these may fluctuate based on the audience segment, content, and other deliverability factors.

- **Corporate Emails**: 
  - Emails that deliver high-value content, such as legal documents or proprietary information.
  - Keeping your corporate email communications on the base domain while using subdomains for other marketing or bulk emails protects their reputation.
