Subdomains: You may use unlimited subdomains on all hosting plans. Databases: The number of databases is listed under each plan above. Database Sizes: There is no explicit table or database size limit, however if the size of your database begins to impede performance on a shared server, we'll let you know that you will need to pare down the size of the database by finding the cause of the increase in size and fixing it, or upgrade to a VPS to continue hosting the database on our shared hosting. With WordPress, a database greater than roughly 500MB - 1GB typically begins to impede server performance. Outgoing Mail Limits: There are limits on the number of messages you're allowed to send each hour. See our knowledge base article for the current limits and what is considered acceptable use of our mail services.
