Threads Email Notifications Going to Spam: Whitelist Steps

Threads email notifications arriving in your spam folder means you miss replies, follows, and quote alerts. This problem happens because your email provider or client misidentifies automated messages from Threads as bulk or suspicious mail. In this article, you will learn why Threads emails land in spam and how to whitelist the sender addresses in Gmail, Outlook, and Apple Mail.

Why Threads Email Notifications Go to Spam

Email providers use automated filters to protect users from bulk senders and phishing attempts. Threads sends notifications from noreply@mail.threads.net and other addresses under the mail.threads.net domain. These messages often lack a prior email thread in your inbox, which makes them appear unsolicited to spam detection engines. Additionally, if you have previously marked a Threads email as spam, the provider learns to treat all future messages from that sender the same way. The fix requires you to whitelist the sender domain and train your email client to trust those messages.

Steps to Whitelist Threads Email Notifications

Complete the steps for your email provider. If you use multiple email clients, repeat the process for each one. Always start by moving any existing Threads email from the spam folder to the inbox before creating a whitelist rule.

Whitelist Threads in Gmail

1. Move existing Threads emails to inbox
   Open Gmail. Go to the Spam folder. Find any email from noreply@mail.threads.net. Select the checkbox next to the email and click the Not spam icon at the top of the page. This action trains Gmail to treat future messages from this sender as legitimate.
2. Create a filter for the Threads domain
   Click the gear icon in the top-right corner and select See all settings. Go to the Filters and Blocked Addresses tab. Click Create a new filter. In the From field, type mail.threads.net. Click Create filter.
3. Set filter actions
   In the filter options, check the box next to Never send it to Spam. Also check the box next to Always mark it as important if you want Threads notifications to appear in the Priority Inbox. Click Create filter to save the rule.
4. Add sender to contacts
   Open any email from Threads. Hover over the sender name Threads at the top of the message. Click Add to Contacts in the pop-up window. This step adds noreply@mail.threads.net to your Google Contacts, which further reduces spam classification.

Whitelist Threads in Outlook and Microsoft 365

1. Move existing Threads emails to inbox
   Open Outlook on the web or the desktop app. Go to the Junk Email folder. Right-click any email from Threads and select Not Junk. A dialog box appears. Check the box next to Also trust email from this sender and click OK.
2. Add sender to Safe Senders list
   In Outlook on the web, click the gear icon and select View all Outlook settings. Go to Mail > Junk email. Under Safe senders and domains, click Add. Type mail.threads.net and press Enter. Click Save at the top of the page. In the Outlook desktop app, go to Home > Junk > Junk E-mail Options > Safe Senders. Click Add, type @mail.threads.net, and click OK.
3. Create an inbox rule
   In Outlook on the web, go to Settings > Mail > Rules. Click Add new rule. Name the rule Threads Notifications. Under When I get an email with all of these conditions, select From and enter mail.threads.net. Under Do all of the following, select Move to and choose Inbox. Click Save.

Whitelist Threads in Apple Mail (macOS and iOS)

1. Move existing Threads emails to inbox
   On macOS, open Apple Mail. Select the Junk folder. Drag any email from Threads to the Inbox folder. On iOS, open the Mail app, tap the Junk folder, tap Edit, select the Threads email, tap Move, and choose Inbox.
2. Add sender to VIP list
   On macOS, open a Threads email. Click the sender name Threads next to the From field. Select Add to VIPs. On iOS, open a Threads email, tap the sender name, and tap Add to VIP. VIP senders bypass the junk filter.
3. Create a rule in macOS Mail
   On macOS, go to Mail > Preferences > Rules. Click Add Rule. Name the rule Threads. Under If any of the following conditions are met, select From Contains and type mail.threads.net. Under Perform the following actions, select Move Message to Inbox. Click OK.

If Threads Emails Still Go to Spam After Whitelisting

If you completed the whitelist steps and Threads emails still land in spam, check these additional factors.

Your email provider uses a strict spam policy

Some corporate or school email accounts apply global spam rules that override personal whitelists. Contact your IT administrator and ask them to add mail.threads.net to the organization’s allowed sender list. For personal accounts, try switching to a different email provider as a workaround.

Threads email notifications are turned off in the app

Open the Threads app on your phone. Go to Profile > the two-line menu icon > Notifications. Under Email notifications, make sure toggles for Replies, Mentions, and Follows are turned on. If email notifications are disabled, Threads will not send any messages for you to whitelist.

Your email address changed or the Threads account is linked to a different email

Threads sends notifications to the email address associated with your Instagram account. Open Instagram, go to Profile > Edit Profile > Personal Information, and verify the email address listed. If you changed your email, update the whitelist rules to match the new address.

Threads Email Notification Types and Spam Risk Compared

Notification Type	Sender Address	Spam Risk
Reply notification	noreply@mail.threads.net	High if no prior email thread exists
Follow notification	noreply@mail.threads.net	High if no prior email thread exists
Quote notification	noreply@mail.threads.net	High if no prior email thread exists
Weekly digest	digest@mail.threads.net	Higher due to bulk-sending pattern

After you whitelist the domain mail.threads.net in your email provider, all notification types listed above should reach your inbox. The weekly digest may still be flagged by some corporate filters because it uses a separate sender address. If you miss only the digest, add digest@mail.threads.net to your contacts or safe senders list separately.

You now know exactly which Threads sender addresses to whitelist and how to configure Gmail, Outlook, and Apple Mail to keep those notifications in your inbox. Start by moving any existing Threads emails out of spam to train your provider. Next, create a filter or rule for the mail.threads.net domain. If you manage multiple email accounts, repeat the process for each one. For advanced protection, also add digest@mail.threads.net to your safe senders list to catch the weekly summary email.
