Why BigCommerce appears in this category
SaaS e-commerce platform (some SMTP for transactional).
We classify it as a hosting mail bundle from primary MX record (lowest preference) matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
BigCommerce is a hosted e-commerce platform operated by BigCommerce Holdings. It provides storefronts, commerce infrastructure, and backend systems for online merchants. When MX records are surveyed across the public internet, BigCommerce appears in the mail routing configuration of many websites, indicating that the platform's mail infrastructure handles these domains' email routing.
In email infrastructure surveys, BigCommerce emerges predominantly among smaller and mid-market retailers rather than major enterprise brands. The MX footprint concentrates in the .com namespace with a global but US-skewed geographic distribution. For email senders and mail operators, this pattern indicates that BigCommerce-hosted domains represent a distinct segment within e-commerce traffic—one worth monitoring separately from large consumer mailbox providers, both for delivery reputation and authentication posture.

Email delivery through partner service providers
BigCommerce-hosted sites frequently route transactional and marketing email through dedicated email service providers, with Mailjet (operated by Sinch) appearing commonly alongside BigCommerce infrastructure in mail configuration surveys. This integration affects the sender's authentication reputation and delivery path; when evaluating email from a BigCommerce site, the actual mail sender identity and reputation often reflect both the platform's infrastructure and the ESP's sending practices. Examining the sending IP's associated domains, SPF records, and DKIM configuration alongside the MX record provides clarity on the true mail path and sender identity.
