Frequently Asked Questions about Vegamailer

Does VegaMailer support both SMTP and API sending, or just one?

VegaMailer handles both SMTP relay and REST API delivery, so you can choose the method that fits your infrastructure without switching platforms. Teams can use whichever approach their application or workflow requires, and manage both through the same console.

Can I set up SPF, DKIM, and DMARC authentication for multiple domains?

Yes, VegaMailer centralizes domain authentication across your sending domains, handling SPF, DKIM, and DMARC checks in one place. The unified console keeps DNS configuration and suppression outcomes visible alongside your sending activity, so authentication and delivery status stay connected to your workflow.

How do scoped credentials work and what do you mean by masked states?

Scoped credentials let you restrict which domains or delivery methods a given API key or SMTP user can access, reducing the blast radius if a credential leaks. VegaMailer masks the actual credential values in the console and provides rotation paths, so you can manage access control without exposing keys across your team.

What happens when an email fails to deliver, and how do I see why?

VegaMailer shows readable failure state explanations in the delivery console, so you can understand whether a send failed due to DNS misconfiguration, a blocked recipient, authentication issues, or other causes. Live delivery metrics and event search let you inspect failures in real-time without exporting raw logs elsewhere.
