SMTP RELAYS / IN DETAIL7 useful answers
What is an OmbraHost SMTP-relay plan?+
The prepared Signal range describes outbound email relay capacity and tier-specific sending-domain limits. A relay does not automatically include domain mailboxes or guarantee inbox placement. Validate sender authentication, permitted recipients and sending quality; outbound email requires a connected relay provider.
Should different mail types share an IP?+
Separate transactional delivery from marketing where possible. Reputation problems in one stream can otherwise affect receipts, security alerts and password recovery.
How does IP warming work?+
The source proposes four to six weeks of gradually increasing permitted traffic. A prepared IP option costs $14.25; inbox placement remains dependent on sending quality.
How many domains can send?+
The proposed domain limits are one, five and twenty-five across Signal 1K, 10K and 50K. Configure an individual DKIM key and aligned DNS for each.
Can a sending application connect?+
Applications supporting custom SMTP can use host, port and credentials once the relay exists. Specific vendor integrations and HTTP APIs are not connected.
What if reputation deteriorates?+
Investigate complaints, bounces, authentication and list quality first. Address rotation must not be used to evade recipient protections or repeat unwanted sending.
What mail is permitted?+
Use valid consent or another verified lawful basis, accurate sender details and a working unsubscribe mechanism. Purchased lists and abusive bulk delivery are prohibited.
