Key facts

Convento is a SaaS platform that transmits email on behalf of domains, enabling organisations to offload their outbound mail handling to a dedicated infrastructure provider. It serves primarily smaller sites and mid-market organisations, particularly concentrated in the German-speaking regions, and appears frequently in email configurations where it operates alongside Microsoft 365 as a complementary sending service.

The presence of Convento SPF include records across the Tranco top-million dataset — clustered in the long tail rather than the largest brands — reflects a common pattern where organisations layer multiple email vendors to meet distinct sending requirements. For anyone sending mail through or validating mail from a Convento-using domain, this shared infrastructure means understanding how third-party transmission platforms integrate into your domain's authentication chain; for receiving mail systems, Convento represents one more authorised sender to validate during SPF, DKIM, and DMARC evaluation.

SPF record management in multi-vendor email stacks

When organisations run Microsoft 365 alongside Convento, their SPF records accumulate include directives from both platforms. This is particularly common amongst smaller organisations that use Microsoft's suite for employee email but route customer-facing or transactional messages through Convento. The resulting SPF chain must be carefully managed; organisations need to monitor their DNS lookup count against the SPF specification's limit, consolidate includes where possible, and ensure proper authorisation ordering. Misconfiguration risks authentication failures when strict validators reject overly complex SPF records, or security degradation if records become inadvertently overpermissive in an attempt to accommodate multiple vendors.
