# IP Delivery Reports
{% hint style="info" %}
**One view to rule them all**
Combined IP address reporting for Velocity MTA and your IP addresses at email service providers such as Mailgun, SparkPost, and Amazon SES that have a webhook integration via an [API connection](https://docs.emaildelivery.com/docs/introduction/connect-mailgun-api).

{% hint style="warning" %}
**Data retention limitations for this report**
IP address data generated by Velocity MTA and API connection webhooks is noisy, and as the number of IP addresses in use grows, so does the volume of data. In order to protect against unpredictable high-usage scenarios that may overwhelm the database, we've imposed a default data retention limitation of 90 days for the platform. If this is a potential concern for you please [contact us](https://emaildeliverycom.freshdesk.com/support/tickets/new).

**Raw Velocity MTA logs are stored forever**
You can access the complete history of your Velocity MTA sending IP addresses in the velocity-install/logs/velocity.log file. Unless you've set up your own log rotation, or otherwise truncate or delete this file, you can always use it to retrace past sending activity. We're working on some helpful tools to assist you in this endeavor.

**Delivery Timeline**
You can drill down into a timeline diagram displaying the delivery history of each IP address for any mailbox provider such as Gmail or Yahoo. This visual aid gives you a unique ability to analyze delivery patterns and closely monitor how reputation fluctuations can impact your email delivery rate over time.
