Don’t Load Remote Images
Most of us get emails with images in them, for example, newsletters, advertisements, confirmations of purchases, or spam. To display the images embedded in each email, your iPhone has to download these images. And since pictures take up more storage space than text, that can add up to a lot of memory used. If you’re okay with your email being a little plain, block your iPhone from downloading this content.
Delete Emails Sooner
When you tap the trash can icon when reading email or swipe across your inbox and tap Delete, you’re not deleting the mail. What you’re actually telling your iPhone is, “the next time you empty the trash, make sure to delete this one.” Email isn’t deleted immediately because the iPhone email settings control how often the iPhone empties its trash. The items that are waiting to be deleted take up space on your phone, so if you delete them sooner, you’ll free up space faster. To change that setting:
Don’t Download Any Email at All
If you want to get extreme or want to use your storage space for something else, don’t set up any email accounts on your iPhone. That way, email will take up 0 MB of your storage. If you don’t set up email accounts, that doesn’t mean you won’t be able to use email on your phone. Instead of using the Mail app, go to the website for your email account (for example, Gmail or Yahoo Mail) in a web browser and log in that way. When you use webmail, no email downloads to your phone.
