The “+1 Gmail trick” (also called the “Gmail plus trick”) uses a small feature in Gmail: you can add a +anything after the username part of your address and still receive the email in the same inbox. For example:

 

 

 

All of these addresses deliver to the same real Gmail account: [email protected].

How the +1 Gmail trick works

Gmail ignores everything after the + sign in the username and also ignores dots in the username. That means:

are all treated as the same mailbox by Gmail, even though many websites see them as “different” email addresses.

Legitimate use: personal filters and organisation

For individual users, this can be handy:

  • Signing up to different services with labels like +shop or +events.
  • Creating filters in Gmail to automatically label or route incoming emails.
  • Seeing which website leaked or sold your email (based on the label used).

Used like this, the trick is fine for personal inbox management.

Why you shouldn’t rely on it in email marketing

For bulk email or bulk email software usage, the +1 Gmail trick is not something you should count on. Here’s why:

1. It doesn’t create “new” subscribers

From Gmail’s point of view, it is always the same real person and the same inbox. Using +labels to “fake” multiple subscribers doesn’t increase your real audience and can distort your statistics.

2. It can break your list quality

If you encourage or accept many +variations of the same Gmail address, you risk:

  • Duplicate “contacts” in your list that all belong to one person.
  • Confusing segmentation and automation logic.
  • Unsubscribe issues (the user unsubscribes one variation, but still gets emails on others).

3. It’s not a safe way to bypass limits or tests

Some people try to use the +1 trick to:

  • Create many test accounts on a platform.
  • Bypass free-plan limits by pretending to be several different users.
  • Seed “fake” signups into their own list.

This is risky: it may violate the terms of service of the platform and doesn’t help your deliverability or ROI. Bulk email providers like Mailpro focus on real, consent-based subscribers, not artificial variations of the same address.

4. It doesn’t fix deliverability or spam issues

If you have deliverability problems, changing your address to [email protected] does not solve the root causes. To send at scale, you need:

  • Proper SMTP infrastructure and bulk email software.
  • Domain authentication (SPF, DKIM, DMARC).
  • Clean, opt-in lists and good sending practices.

Better alternatives for marketers

Instead of relying on the +1 Gmail trick, focus on:

Summary: what you should remember

The +1 Gmail trick is a clever feature for individuals to organise their inbox, but it is not a solid strategy for email marketing. It does not create new real subscribers, can damage your data quality, and won’t fix deliverability issues. For sending bulk emails safely, use a dedicated bulk email software like Mailpro, follow best practices, and focus on genuine, long-term relationships with your subscribers.
