- SSL-Secured Links & Domain Masking: Protects links and makes URLs look professional, building trust with recipients.
- Controlled Send Volumes: Caps daily emails per mailbox to avoid spam flags and preserves your sender reputation.
- Reputation Monitoring: Tracks metrics like bounces and open rates, alerting you to potential issues.
With Mailforge handling the technical side, AI SDRs like Agent Frank can focus on crafting personalized outreach while ensuring emails land in inboxes, not spam.
Automated DNS Authentication: SPF, DKIM, and DMARC Setup
Email authentication protocols act like digital ID checks, ensuring that emails come from legitimate sources. For AI SDRs sending thousands of emails daily, these protocols are critical to proving authenticity to email providers like Gmail, Outlook, and Yahoo. Without proper setup, even the best-crafted emails can end up in spam folders. Here’s how Mailforge simplifies and automates these processes to keep emails on track.
Manual configuration of these protocols often leads to errors, misaligned records, and failed authentication, all of which can harm your sender reputation. For businesses scaling their outreach, handling this manually becomes a major hurdle to effective email delivery.
How SPF, DKIM, and DMARC Work Together
SPF (Sender Policy Framework) ensures that only authorized IP addresses can send emails on behalf of a domain. When an email server receives a message, it checks the SPF record in the sender's DNS to confirm the sending IP is permitted.
DKIM (DomainKeys Identified Mail) adds a digital signature to each outgoing email. This signature is created using a private key stored on the sending server, while a corresponding public key is published in the domain's DNS records. The receiving server uses this public key to verify that the email hasn’t been tampered with and is genuinely from the claimed sender.
DMARC (Domain-based Message Authentication, Reporting and Conformance) acts as the policy layer, tying SPF and DKIM together. It instructs receiving servers on what to do if an email fails SPF or DKIM checks - whether to deliver, quarantine, or reject it.
Together, these protocols create a robust authentication framework. SPF verifies the source, DKIM ensures the message’s integrity, and DMARC enforces policies and provides visibility. When properly configured, this trio not only boosts email deliverability but also shields against spoofing attacks.
Mailforge's Automated Configuration Process
Mailforge takes the complexity out of setting up these protocols by automating the entire process. When users create new domains and mailboxes, the platform instantly generates and publishes the necessary SPF, DKIM, and DMARC records, removing the need for manual input.
The automation kicks in as soon as a new domain is added to a Mailforge workspace. SPF records are created to specifically authorize Mailforge’s sending infrastructure, optimized for cold email campaigns to balance security and deliverability.
For DKIM, Mailforge generates unique cryptographic key pairs for each domain and automatically publishes the public keys in the DNS records. The platform handles key rotation and updates behind the scenes, ensuring that digital signatures remain valid and trusted by email providers. This automated management prevents common issues like mismatched selectors or expired keys, which can lead to failed authentication.
Mailforge also streamlines DMARC setup by applying policies tailored to the domain’s purpose. It starts with a monitoring mode to observe authentication performance and allows for adjustments as needed. This gradual approach avoids overly strict policies that could block legitimate emails while still protecting against spoofing attempts.
For businesses managing multiple domains, Mailforge offers tools to update DNS records across all domains simultaneously. This feature is invaluable for scaling AI SDR operations, where manual updates would be both time-consuming and prone to errors. Changes are applied consistently across Mailforge’s infrastructure, ensuring reliable authentication for all sending domains.
Beyond initial setup, Mailforge continuously monitors DNS records and makes adjustments as needed. This includes updating SPF records when IP addresses change, rotating DKIM keys on schedule, and fine-tuning DMARC policies based on performance metrics. By handling these tasks automatically, Mailforge ensures optimal deliverability without requiring user intervention.
With these systems in place, Agent Frank operates within a trusted and authenticated email environment. Users can dedicate their time to crafting impactful outreach campaigns, confident that Mailforge is managing the technical details to keep their emails out of spam folders and in front of their intended recipients.
SSL-Secured Redirection and Domain Masking
When AI-driven Sales Development Representatives (SDRs) send thousands of emails daily, every link click becomes a critical checkpoint for security. Both email providers and recipients closely examine not just the content of the email but also the safety of any embedded links. SSL-secured redirection and domain masking create an essential layer of security that not only protects users but also boosts credibility and professionalism. These technologies work quietly in the background, ensuring every interaction feels safe and trustworthy.
Link handling plays a big role in email security. Recipients today are more cautious than ever about clicking links, especially if the sender isn’t familiar. Suspicious-looking URLs or redirects through unknown domains can trigger spam filters and erode trust before a conversation even begins.
Why SSL and Domain Masking Matter
SSL encryption ensures that data exchanged when recipients click on links remains secure, guarding it against interception. When a link is clicked, browsers check for valid SSL certificates. If a certificate is missing or invalid, the recipient may see a browser warning, which can hurt engagement and damage the sender's reputation.
Email providers like Gmail and Outlook use SSL verification as part of their spam detection algorithms. Links without proper SSL certificates are often flagged, increasing the likelihood of emails landing in spam folders. Domain masking further enhances security by presenting links as part of a branded domain rather than a generic tracking URL. This not only builds trust but also reinforces the sender’s brand.
Together, SSL encryption and domain masking help reduce risks commonly associated with cold email campaigns. Phishing attacks often exploit unsecured redirect chains, but by using these measures, legitimate senders can stand apart from malicious actors. Additionally, SSL encryption protects recipients' privacy by safeguarding their browsing behavior and personal information during the redirect process.
How Mailforge Handles SSL and Domain Masking
Mailforge simplifies the process by automatically integrating SSL certificates and domain masking into its platform. Users don’t have to worry about manually managing these security features. When a domain is added to Mailforge, SSL certificates are automatically issued, maintained, and renewed - ensuring uninterrupted protection without the risk of certificate expiration.
Domain masking is seamlessly implemented through Mailforge’s redirect system. This ensures that links appear under user-controlled domains while retaining full tracking capabilities. For recipients, this means seeing URLs that match the sender’s domain instead of generic tracking links, creating a more professional and consistent brand experience.
For Agent Frank’s AI-generated campaigns, this system works effortlessly. Just as automated DNS authentication secures outbound emails, SSL-secured links and domain masking protect every click. This allows the AI to focus on crafting compelling messages, while Mailforge ensures that every link meets strict security standards and looks professional.
Mailforge offers SSL and domain masking as an optional service, priced at $2 per domain per month for monthly billing or $6 per domain per year for annual billing. This flexible pricing makes it easy for businesses to scale their security measures alongside their growing domain portfolios.
Controlled Send Volume and Reputation Monitoring
Email providers like Gmail, Outlook, and Yahoo rely on algorithms to monitor sending patterns and flag potential spam sources. When you're sending thousands of emails daily, managing the volume carefully is essential to protect your sender reputation. Sending too many emails too quickly can get your domain flagged, while sending too few might hinder your outreach efforts. The trick is finding that perfect balance where your emails maintain high deliverability while still scaling effectively.
These providers keep a close eye on sudden spikes in email volume or high bounce rates, which can trigger spam filters. By adopting a controlled and steady approach, you can ensure optimal sending limits and maintain centralized monitoring for consistent results.
Optimal Send Limits for AI SDRs
Mailforge sets a limit of 15 emails per day per mailbox, striking the right balance between volume and deliverability. This cap helps maintain a strong sender reputation with major email providers. Instead of overloading one mailbox, businesses can scale their outreach by using multiple mailboxes.
