iCloud SMTP Settings

Setting up your icloud smtp can feel tricky, but you can do it with the right information. Let’s break down the icloud smtp settings you need for any email client.
Server Details
You need to enter the correct smtp server settings to send mail from your icloud account. The official icloud smtp server is easy to remember. Here’s a quick table to help you see the details:
Server Name | Port Number | SSL Required | Authentication Required |
|---|---|---|---|
smtp.mail.me.com | 587 | Yes | Yes |
You can also use port 465 for smtp connections, but most email clients work best with port 587. Both ports use SSL to keep your messages safe. When you set up your icloud mail, always choose SSL or TLS if your email app asks.
Username and Password
You must use your full icloud email address as the username. For the password, you cannot use your regular icloud password. Apple wants you to keep your account secure, so you need an app-specific password. This password works only for your email app, not for other icloud services.
Tip: If you have not turned on two-factor authentication for your icloud account, you need to do that first. Apple requires it before you can make an app-specific password.
Why does Apple ask for these extra steps? Here’s why:
Two-factor authentication adds another layer of security. Even if someone gets your password, they cannot get into your account without your phone or trusted device.
App-specific passwords limit access. Your email app gets only what it needs, so your main icloud account stays safe.
If someone steals your password, two-factor authentication blocks them from logging in.
You need these icloud smtp settings for any third-party email client. Gmail, Outlook, Thunderbird, and others all require this setup.
SSL and Port
SSL keeps your messages private when you send them through smtp. You should always turn on SSL or TLS in your email client. Here’s a table with the port numbers and protocols Apple recommends for icloud smtp:
Port Number | Protocol | Description | Usage |
|---|---|---|---|
465 | TCP | Authenticated SMTP | Sending mail |
587 | TCP | Authenticated SMTP | iCloud Mail (SMTP authentication) |
993 | TCP | IMAP SSL | iCloud Mail (SSL IMAP) |
995 | TCP, UDP | POP SSL | — |
Most users pick port 587 for icloud smtp because it works with almost every email client. Always check that SSL is enabled in your settings.
You might wonder how icloud smtp compares to other providers. Apple, Google, and Microsoft all want you to use secure connections. They ask for authentication and encryption to keep your emails safe. Here’s a quick look:
Provider | SPF Requirement | DKIM Requirement | DMARC Policy | TLS Encryption |
|---|---|---|---|---|
Google (Gmail) | Required for all senders | Required for all senders | At least p=none for bulk senders | Required for all senders |
Microsoft (Outlook) | Required for bulk senders | Required for bulk senders | At least p=none for bulk senders | N/A |
Apple (iCloud Mail) | Required for bulk senders | Required for bulk senders | At least p=none for bulk senders | Not specified |
You need to follow these icloud smtp settings for every email client outside Apple Mail. This setup keeps your messages secure and helps your emails reach the inbox.
Configure iCloud SMTP in Email Clients

Setting up icloud smtp in your favorite email app is easier than you think. You just need to follow a few steps. Let’s walk through the process together so you can send and receive icloud mail anywhere.
Enable Two-Factor Authentication
Before you can use smtp icloud settings, you need to turn on two-factor authentication for your icloud account. This step keeps your account safe and gives you peace of mind.
On Your iPhone, iPad, or iPod Touch
Open Settings.
Tap your name at the top.
Select Password & Security.
Tap Turn On Two-Factor Authentication.
Enter your trusted phone number.
Type in the verification code you receive.
On Your Mac
Open System Preferences.
Click Apple ID.
Go to Password & Security.
Turn On Two-Factor Authentication.
Enter your trusted phone number.
Type in the verification code.
Tip: Two-factor authentication adds an extra layer of protection. Even if someone knows your password, they can’t get into your icloud account without your phone.
When you enable two-factor authentication, you make it much harder for anyone to break into your icloud mail. You get enhanced security and peace of mind every time you use icloud smtp.
Generate App-Specific Password
You can’t use your regular icloud password for smtp. Apple wants you to create an app-specific password for each email app you use. This keeps your main account safe.
Here’s how you generate an app-specific password:
Go to appleid.apple.com and sign in with your icloud account.
Find the Security section.
Click Generate Password under App-Specific Passwords.
Type a label for the password (like “Outlook” or “Thunderbird”).
Copy the password Apple gives you.
If you ever change your main Apple ID password, all your app-specific passwords stop working. You’ll need to make new ones for each app you want to use.
App-specific passwords let you use icloud smtp in third-party email clients without giving them full access to your icloud account. This keeps your information safe and private.
Enter SMTP iCloud Settings
Now you’re ready to configure icloud smtp in your email client. You need to enter the correct icloud smtp settings so your messages send without problems.
Here’s what you do in popular email apps:
Gmail
Log in to your Gmail account.
Click the gear icon and choose See all settings.
Go to Accounts and Import.
Click Add another email address under “Send mail as.”
Enter your name and icloud email address.
Uncheck Treat as an alias.
Enter the icloud smtp settings:
SMTP Server: smtp.mail.me.com
Port: 587
SSL: Yes
Username: Your full icloud email address
Password: Your app-specific password
Click Add Account.
Gmail sends a verification code to your icloud mail. Enter the code to finish setup.
Outlook
Open Outlook and go to File > Add Account.
Enter your icloud email address.
Choose Manual setup or additional server types.
Select POP or IMAP.
Enter the icloud smtp settings:
SMTP Server: smtp.mail.me.com
Port: 587
SSL: Yes
Username: Your full icloud email address
Password: Your app-specific password
Save your configuration.
Thunderbird
Open Thunderbird.
Click Add Mail Account under Account Actions.
Enter your icloud email address and app-specific password.
Enter the icloud smtp settings:
SMTP Server: smtp.mail.me.com
Port: 587
SSL: Yes
Username: Your full icloud email address
Password: Your app-specific password
Finish the setup.
The steps for configuring icloud smtp may look a little different depending on your email client. Always check for options like SSL, port number, and authentication. If you use a mobile app, you might need to go to advanced settings and enter the smtp server settings manually.
You can use icloud smtp in almost any email client. Just remember to use your app-specific password and double-check your configuration. If you want to manage multiple icloud accounts or improve deliverability, platforms like Mails.ai make it easy to rotate inboxes and keep your emails out of spam.
Troubleshooting iCloud SMTP
Running into problems with your icloud smtp setup? You’re not alone. Many users hit a few bumps when trying to send mail from third-party apps. Let’s look at the most common issues and how you can fix them.
Common Issues
You might see error messages or have trouble connecting when you set up icloud smtp. Here are some problems you could face:
554 5.7.1 Access Denied: This means your connection got blocked, often because of your IP address.
Incorrect Server Selection: Picking the wrong smtp server settings can stop your emails from sending.
App-Specific Password Requirement: If you skip the app-specific password, your configuration won’t work.
To avoid these headaches, double-check these smtp icloud settings:
SSL Requirement: Yes (if SSL fails, try TLS or STARTTLS)
Port: 587
SMTP Authentication: Required
Username: Your full icloud email address
Password: Use the app-specific password you created
If you run into SSL problems, try these steps:
Open your mail app’s account settings.
Turn off “Automatically manage connection settings.”
Make sure “Use TLS/SSL” is checked.
Set the port to 587.
Save your changes.
Tip: Always use the latest version of your email client for the best compatibility with icloud smtp.
Sending Limits
Apple sets limits on how many emails you can send with icloud smtp. If you hit these caps, your messages might not go through. Here’s a quick look:
Provider | Daily Limit | Recipients per Message |
|---|---|---|
iCloud Mail | 1,000 | 500 |
Gmail | 500 | 500 |
Outlook.com | 10,000 | N/A |

If you need to send more than 1,000 emails a day, icloud smtp may not be the right fit.
Personal Use Restrictions
Apple designed icloud smtp for personal use. You can send up to 1,000 emails per day and reach a maximum of 500 recipients per message. If you try to send bulk or commercial emails, you might see your account restricted.
iCloud smtp is not for mass marketing or business campaigns.
