Why Is Apple Mail So Slow? (9 Reasons Why)

If you have been trying to load Apple Mail but it’s lagging, you may be wondering: why is Apple Mail so slow? 

Well, I have been looking into this question and have found some of the most common reasons, so keep reading to learn what I’ve discovered about this problem! 

Why Is Apple Mail So Slow in 2024?

Apple Mail might be slow because of your Internet connection, like if you’re home using your Wi-Fi in 2024. Additionally, there could be apps running in the background causing Apple Mail to be slow or not respond. Also, having multiple email accounts synced with Apple Mail could cause delays in the app loading your emails. 

Do you want to know all the possible reasons why Apple Mail is so slow? If so, don’t stop reading because I have even more possible explanations below! 

1. Your Internet Connection Is Slow or Timed Out 

If you’ve noticed Apple Mail is slow, it could be because your Internet connection is slow or has timed out, which is common if you have a lot of devices connected to your Wi-Fi. 

Therefore, it’s a good idea to limit the number of devices connected to your Wi-Fi to ensure that you’re getting the best speeds possible on your iOS device.

2. Too Many Apps Running in the Background 

Apple Mail might be slow because you have too many apps running in the background, which causes lag and can bog down the memory on your device. 

For example, if you have a game or streaming service running, it’ll cause Apple Mail to load slower, since so much memory and RAM is devoted to these graphically-intense apps. 

3. You Have More Than One App Using That Email Account 

If you have multiple apps that use that email account, it can cause conflicts and prevent Apple Mail from loading that email account properly. 

Consequently, you want to try to limit the number of apps that access that email account so that it doesn’t create a conflict with Apple Mail. 

4. You Have Multiple Emails Synced to Apple Mail 

The more email accounts you have synced with Apple Mail, the slower Apple Mail might be, like if you have multiple Yahoo and Gmail accounts linked to it. 

Furthermore, having them set up to sync and be checked at the same time just means it’ll take longer to connect to the servers and load your messages. 

5. Your iPhone Is Glitching 

Your iPhone Is Glitching 

Sometimes the issue might not be with Apple Mail itself, but with your iPhone, like if there’s a glitch with your iPhone causing the problem with Apple Mail. 

Therefore, it’s important to restart your device regularly to prevent glitches and bugs from occurring that could lead to Apple Mail being slow. 

6. There Is an Outage With Your Email Service Provider 

If Apple Mail is slow, the issue could be an outage with your email service provider or another issue affecting your email provider that’s preventing messages from appearing. 

Also, you can use a website such as Down Detector to see if an outage is occurring with your email provider, but there’s not much you can do except wait until the issue has been resolved. 

7. Your Data Signal Is Weak 

If you’re using your iPhone and data, you might have a weak signal preventing Apple Mail from loading correctly or quickly, like only having two bars instead of three or four. 

That being said, it’s simple to see if this is the issue just by moving to a new location with a better signal and then trying to reload Apple Mail to see if it works. 

8. Your iPhone Network Settings Are Glitching 

The network settings on your iPhone might be the issue if Apple Mail is slow, so resetting the network settings could help speed up Apple Mail. 

Furthermore, it’s simple to reset the network settings on your iPhone by following our guide below: 

  1. Go into “Settings” on your iOS device
  2. Select “General”
  3. Click on “Reset” 
  4. Select “Reset Network Settings” 

However, when you reset the network settings, you’ll need to enter your password again for your networks, so make sure you know what they are before you perform this fix. 

9. Mail Preview Slows Down Apple Mail 

If you have Mail Preview enabled, it can slow down Apple Mail, especially if you’re someone that gets a lot of emails. 

Therefore, if you disable Mail Preview, it can improve performance and speed up Apple Mail, especially if you’re on an older device or don’t have much space on your device.

Conclusion 

If Apple Mail is slow, it could be because you have Mail Preview enabled or an outage with your email provider. In addition, Apple Mail will run slow if you have multiple apps running in the background or if you’re in an area where you have a weak data signal. 

However, Apple Mail could be slow because your iPhone itself is glitching, so regularly restart to get the best performance possible out of your iPhone.
