1. Email Service Providers (ESPs): Companies like Mailchimp, Constant Contact, and Sendinblue that offer platforms to create, send, and track emails. 2. SMTP Servers: Simple Mail Transfer Protocol servers handle the sending of emails. They ensure the emails are routed correctly and delivered to the recipient's inbox. 3. DNS and MX Records: Domain Name System and Mail Exchange records direct the emails to the appropriate servers. 4. Anti-Spam Technologies: Tools and protocols that help in identifying and filtering out spam, ensuring legitimate emails reach the intended recipients.
