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, discarding 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. For optimal performance, Google recommends that you use fewer than 500 labels (including nested labels) in your account and use search and filters to help find messages. When transitioning to a G Suite 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.
- Reduce Inbox messages. Too many messages in the Gmail inbox can cause some Gmail features to stop working. The Gmail right-click menu is not available when there are 250,000 or more messages in the inbox.
- Know the limits. To help keep 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 G Suite account. These limits do not inhibit normal email use, but are designed to help identify any misuse of Gmail. For more information, see:
