Follow these recommended practices to get the best performance from your Gmail account:
- Avoid bulk operations. Select less than a thousand messages at a time when performing operations such as deleting email, expunging trash, applying labels, or archiving messages.
- Use search in Gmail. Use Search in Gmail the same way you use Google to search the web. Type in keywords to find messages in your account.
- Use filters. Use filters to narrow or target searches in Gmail. Filters can also be used to automatically sort and apply labels to mail.
- Reduce labels. Too many labels can slow processing. Use less than 500 labels (including nested labels) in your account and use search and filters to help find messages. When transitioning to Google Apps account, merge your mail folders before migrating old email into Gmail. For fine-grained organization after a data migration, try using multiple labels per message rather than creating exclusive labels.
To help keep our systems healthy and your account safe, Google limits the amount of bandwidth, storage space, server requests, and number of emails that users can send or receive in their Google Apps account. These limits do not inhibit normal email use, but are designed to help identify any misuse of Gmail.
The following policies have more information on each limit, including best practices to help avoiding reaching these limits:
