Technical Configuration
This section is your hub for configuring your domain's DNS and email infrastructure. The guides here help you properly configure your domain's DNS settings for optimal email delivery and authentication.
Start with authentication
If your mail is landing in spam, the most impactful first step is configuring SPF, DKIM and DMARC. These three records prove your messages are legitimately sent on behalf of your domain.
DNS Authentication Records
These three authentication protocols verify that mail claiming to come from your domain is genuinely authorized — the foundation of reliable deliverability.
| Record | What it does |
|---|---|
| SPF Records | Configure Sender Policy Framework records to declare which servers may send mail for your domain. |
| DKIM Records | Set up DomainKeys Identified Mail so receivers can cryptographically verify your messages. |
| DMARC Records | Configure Domain-based Message Authentication to set policy and receive reports. |
Email Infrastructure
Beyond authentication, these resources help you manage how your mail is sent and how it's perceived by receiving servers.
| Topic | What it covers |
|---|---|
| IP Reputation Management | Understand and maintain your sending reputation over time. |
| SMTP API | Send email programmatically from your applications. |
