Every email provider has a spam folder, and every one of them sometimes gets it wrong. A confirmation email from a small sender (like us) is especially likely to land there, because the sending server is new and has not built up a long reputation yet. That does not mean the email is unsafe. It means the filter is being cautious.

Here is how to fix it in the email clients people actually use.

Gmail (browser)

1. Open Gmail and look at the left sidebar. Click More if you do not see all the folders.
2. Click Spam.
3. Find the email you are looking for. Open it.
4. At the top of the message, click Report not spam (or Not spam). Gmail moves it to your inbox.
5. To make sure future emails land correctly: open the rescued email, click the three dots in the top right of the message, and choose Filter messages like these. In the filter dialog, click Create filter, then check Never send it to Spam and click Create filter again.

Gmail (Android / iOS app)

1. Tap the hamburger menu (three lines, top left).
2. Scroll down and tap Spam.
3. Open the email.
4. Tap Report not spam (or Not spam) at the top of the message.
5. To prevent future filtering: add the sender’s email address to your Contacts. Gmail trusts addresses in your contact list.

Outlook.com / Hotmail (browser)

1. In the left sidebar, click Junk Email.
2. Find the email, right-click it, and choose Move > Inbox.
3. To trust the sender going forward: go to Settings (gear icon, top right) > Mail > Junk email. Under Safe senders and domains, click Add and type the sender’s email address or domain. Click Save.

Outlook desktop (Windows / Mac)

1. In the left folder list, click Junk Email.
2. Right-click the message and choose Junk > Not Junk. Outlook moves it to your inbox and asks if you want to trust the sender. Say yes.
3. Alternatively: drag the message from Junk Email to your Inbox.

Apple Mail (iPhone / iPad)

1. Open the Mail app.
2. Go to your account’s Junk folder (tap Mailboxes at the top left if you do not see it).
3. Open the email.
4. Tap the folder icon (bottom toolbar) and move it to Inbox.
5. To prevent future filtering: tap the sender’s name or address at the top of the email, then tap Add to Contacts or Add to VIPs. Mail trusts addresses you have saved.

Apple Mail (Mac)

1. In the sidebar, click Junk under your email account.
2. Select the message.
3. In the toolbar, click Not Junk. (If you do not see the button, right-click the message and choose Move to Inbox.)
4. Add the sender to your Contacts to prevent future filtering.

Proton Mail (browser or app)

1. In the left sidebar, click Spam.
2. Select the message.
3. Click Move to inbox (or the inbox icon in the toolbar).
4. Proton learns from this and is less likely to filter that sender again.
5. For extra certainty: go to Settings > Filters and add a rule that keeps mail from that address in your inbox.

Yahoo Mail

1. In the left sidebar, click Spam.
2. Open the email.
3. Click Not Spam at the top of the message. Yahoo moves it to your inbox.
4. Add the sender to your Contacts to make sure future emails arrive.

Thunderbird (desktop)

1. In the folder list, click Junk (or Spam, depending on your provider).
2. Select the message.
3. Click the Not Junk button in the toolbar (or right-click and choose Mark > As Not Junk).
4. Thunderbird’s filter learns from this correction and adjusts over time.

Why does this happen?

Email providers use spam filters to protect you from unwanted messages. These filters look at several things: whether the sending server has a long track record, whether other people have marked similar messages as spam, and whether the email’s technical credentials (SPF, DKIM, DMARC) check out.

A new or small sender can have perfect credentials and still land in spam, simply because the filter has not seen enough mail from them yet to trust them. Every time you mark a message “not spam” or add the sender to your contacts, you are telling your email provider: “I asked for this. Let it through.”

That is why your help matters. The more people who rescue the confirmation email and mark it as wanted, the faster the sending reputation builds, and the fewer people have to dig through spam in the future.
