SendGrid handles high-volume email delivery, email campaign management, AI assistance and integration support with partners for wealth management firms. Like every system in your stack it holds a slice of the firm — email campaigns, APIs, documentation and help center — under its own export limits, retention rules and terms governing what you may do with your own information. Milemarker takes the other approach. Your records stay in a Snowflake environment your firm owns, and SendGrid is driven from it as events occur, rather than a standing copy sitting in another vendor's system. That keeps one governed source behind everything — row-level entitlements, PII masking and SOC 2 Type II controls you set — applied whether someone is reading a dashboard or a message in SendGrid.
