To add a “safe sender” in Gmail, you basically teach Gmail: “Emails from this address or domain should never go to Spam.” This is done with filters and (optionally) Google Contacts.

What “safe sender” means in Gmail

  • Gmail does not have a button literally labeled Safe Sender like some other email services.
  • Instead, you:
    • Create a filter that tells Gmail: Never send it to Spam for that sender or domain.
    • Optionally add the sender to Google Contacts so Gmail treats them as more trusted.

Method 1: Safe sender via filter (web)

Use this if you want a reliable, Gmail-style “whitelist” for a person or entire domain.

  1. Open Gmail on a computer and log in.
  2. Click the gear icon (Settings) in the top right, then choose See all settings.
  1. Go to the Filters and Blocked Addresses tab.
  1. Click Create a new filter.
  1. In the From field:
    • Type a specific address (for example: [email protected]), or
    • Type a domain (for example: @example.com) to allow everyone from that domain.
  1. Click Create filter (at the bottom right of the dialog).
  1. On the next screen, check Never send it to Spam.
    • Optionally also check Always mark it as important or apply a label if you want.
  1. Click Create filter again to save.

From now on, messages that match that address or domain will bypass Spam and land in your Inbox.

Method 2: Mark from Inbox or Spam

This is the “quick fix” when a specific email is already in Spam or keeps getting filtered.

  • If the email is in Spam :
    • Open the message.
    • Click Not spam at the top of the message.
    • Gmail learns from this action and is less likely to send emails from that sender to Spam in the future.
  • If the email is in Inbox but you want to secure it:
    • Open the email.
    • Use More (three dots) → Filter messages like this , then:
    • Confirm the sender in the From field → Create filter → check Never send it to Spam → Create filter.

This is basically a shortcut into the same filter process described above, from the actual message.

Method 3: Add to Google Contacts

Adding someone to Contacts is a lighter “trust signal,” and some guides present this as a kind of soft safe list, especially on mobile.

On desktop

  1. In Gmail, open an email from the sender.
  2. Hover over their name or email in the message.
  3. In the contact card that appears, click Add to contacts.

On mobile (Gmail app)

  1. Open the email in the Gmail app.
  2. Tap the sender’s profile icon.
  3. Tap Add to contacts or the contact icon.
  4. A Google Contacts page opens in your browser; tap Save.

This does not guarantee they will never hit Spam, but combined with filters it makes their emails far more likely to reach your Inbox.

Method 4: Safe sender for a whole domain

If your issue is with a company (e.g., all mail from @company.com), you can add the entire domain in one go.

  1. Go to Settings → See all settings → Filters and Blocked Addresses → Create a new filter.
  1. In From , type:
    • *@domain.com or @domain.com (many guides show either pattern, both are used in practice).
  1. Click Create filter.
  2. Check Never send it to Spam.
  3. Click Create filter again.

You can even combine multiple addresses/domains using OR , like:
[email protected] OR *@b.com in the From field.
