However, now that Google Workspace and Outlook 365 are making serious inroads into the corporate email market, B2B email deliverability is behaving more like deliverability for B2C brands.
That means inbox placement—i.e., reaching the inbox of recipients—is increasingly unifying around seven core email deliverability factors:
- Infrastructure: The servers, setup, and controls used by a company’s email service provider (ESP) are important, as is authentication (SPF, DKIM, and DMARC).
- Volume: The higher your email volume and the more erratic your sending patterns, the more scrutiny you can expect from mailbox providers.
