Why BigCommerce appears in this category
BigCommerce — US SaaS e-commerce platform sending order, shipping and account emails for merchant stores.
We classify it as a SaaS sender from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
BigCommerce is a SaaS e-commerce platform operated by BigCommerce Inc. that hosts online retail storefronts and sends transactional and promotional email on behalf of its customer domains. Merchants use it for storefront hosting, payment processing, and order fulfilment, with BigCommerce's infrastructure handling the actual mail transmission.
BigCommerce's email footprint is concentrated among small and mid-market online retailers rather than large enterprise brands, predominantly in the .com domain space with a US and global geographic skew. For email practitioners, this means frequent SPF includes pointing to BigCommerce infrastructure, especially in environments where merchants pair BigCommerce with Microsoft 365 for corporate email—a configuration that can complicate SPF chains and DMARC alignment if not carefully ordered.

SPF includes and DMARC alignment with BigCommerce
Merchants using BigCommerce for email transmission add a BigCommerce SPF include to their domain's SPF record, typically include:bigcommerce.com. When a merchant also operates Microsoft 365, multiple SPF includes compete within the same policy, and if DMARC alignment is not properly configured—such as specifying BigCommerce's signing domain in authentication tags or relaxing alignment—authentication can fail and mail may be rejected or flagged as phishing risk.
