Why DKIM, bounces and complaints matter for transactional email

The essentials

Email is only reliable when the sender domain is authenticated, failures are monitored and problematic recipients stop receiving mail. Mailforge applies these controls to Mailu and SES nodes.

Verify the domain with DKIM

Before sending, the organization publishes SPF, DKIM and DMARC for the selected route. Mailforge keeps a domain unavailable until authentication and traffic-class assignment are validated.

Track every event

“Sent” does not always mean “delivered.” Sending nodes produce separate send, delivery, rejection, bounce and complaint events. Mailforge receives them and links them to the relevant log.

Stop risky sending

A hard-bouncing address must not be retried without correction. A complaint means the recipient considered the message unwanted. Suppressing these addresses protects recipients and the reputation of every sender.

Separated, controlled traffic

Mailforge separates transactional, newsletter and B2B outreach traffic. Campaigns require documented recipient origin and lawful basis, working unsubscribe handling and progressive warm-up. Purchased, rented or scraped lists and unsolicited outreach remain prohibited.

Before requesting access

Prepare a domain you control, accurately describe where recipients come from and estimate your volume. Forge Labs reviews these elements before activation.
