SPF is a security protocol that allows you to verify the identity of the sender by specifying which servers are authorized to send emails on behalf of your domain.

To set up SPF, you need to create a record in your domain's DNS, following the standard format defined by the protocol.

DKIM is a security protocol that provides a digital signature that verifies the integrity of the message during transmission.

To set up DKIM, you need to create a pair of public and private keys, store the private key on the sending server and publish the public key in your domain's DNS.

DMARC is a security protocol based on SPF and DKIM, allowing senders to establish management policies for emails that do not pass authentication checks.

To configure DMARC, you need to create a record in your domain's DNS, defining policies and reporting preferences, following the standard format defined by the protocol.

In 2024, Google and Yahoo introduced new anti-spam regulations that significantly affect bulk mail senders, emphasizing the importance of authentication and user consent.

• Authentication: Compliance with SPF, DKIM and DMARC is crucial to guarantee delivery.

• User consent: A clear and simple unsubscribe option is required.

• Spam limits: It is essential to know and respect the established limits to avoid being classified as spam.

Using subdomains allows you to segment different types of emails (marketing, transactional, newsletters), facilitating independent reputation management for each communication flow.

Subdomains make it easier to identify and resolve problems, such as blacklisting, and make it possible to implement stricter protocols for specific types of emails, improving security and regulatory compliance.

Subdomains can also help improve delivery rates by reducing the risk of emails being filtered as spam by email service providers.

The GDPR is the European regulation that aims to protect the personal data and privacy of EU citizens.

The GDPR requires that consent to email communication be clear, informed and freely given. This means that senders must use clear language in subscription forms, offer separate options for different types of communications and keep records of the consent obtained.

The GDPR also grants subscribers the right to be forgotten, which means that senders must implement a simple process so that subscribers can withdraw their consent and unsubscribe from communications.

In addition, GDPR implies data minimization and transparency, which means that senders must collect only the necessary data and be transparent about its use, storage and protection.

To avoid emails being marked as spam, senders should follow good email sending practices, such as using security protocols, maintaining a good reputation, obtaining explicit consent, respecting unsubscribe options, sending quality content, using clear and precise subject lines, avoiding keywords, links or images associated with spam, using a suitable format and encoding, avoiding suspicious attachments, using domains and IPs and regularly monitor delivery, rejection and complaint rates.
