An effective email infrastructure includes several components:
SMTP Servers: These are responsible for sending out emails. A reliable SMTP server is crucial for ensuring that emails are delivered quickly and efficiently. IP Addresses: Dedicated IPs can help establish a positive sender reputation, essential for improving deliverability. Domain Authentication: Techniques like SPF, DKIM, and DMARC help verify the senderâs identity and protect against spoofing. Email Service Providers (ESPs): These platforms offer tools and infrastructure for managing email campaigns, from design to delivery and analytics.
