Category Statistics
Never put PII in categories
Twilio treats categories as not personally identifiable information (PII). You can't redact or remove this data. Never place PII in this property. Twilio might use this data for operations as it runs its systems. This value may be visible to Twilio employees, stored long-term, and remain after you've left this platform.
Daily category limits
Twilio SendGrid limits the number of stored category statistics available per user. Accounts on a paid plan can create 1,000 categories daily. Accounts on a free plan can create 100 categories daily. To learn more about this, see Limitations.
Categories can help organize your email analytics by enabling you to "tag" emails by type. Just as you can view the statistics on all your email activity, you can go a step further and view the statistics broken down to a particular category.
Info
Category statistics are available for the previous thirteen months only.
The actual statistics included vary depending upon your account settings. Emails sent, bounces, and spam reports will always get tracked. Unsubscribes, clicks, and opens require that the associated settings are enabled.
To see statistics for a category, select the category and the page will show you both a graph and a table of your category's email statistics.
You can change which metrics, date, or grouping by adjusting the statistics filters.
The figures table gives you all of the specific counts or percentages of each event, according to how you've grouped your statistics (day, week, or month). For example, if you wanted to see what percentage of the emails you sent were actually opened on the second week of April, this is a great place to check.
This table will refresh with new or adjusted data based on the various filters available at the top of the page. You can also choose to show actual counts or percentages, by clicking the corresponding button above and to the right of the table.
