Email deliverability test – see where your emails actually land

Why this test exists

An email marked as “delivered” isn’t necessarily sitting in the inbox.

Mailbox providers like Gmail, Outlook, and Yahoo decide where incoming messages belong based on hundreds of signals, including sender reputation, authentication, content quality, and engagement history.

That means an email can be technically delivered while still landing in spam, promotions, or another filtered folder. Our Email Deliverability Test shows where your emails actually land and highlights issues that may be affecting inbox placement before they impact your campaigns.

What we check

• Inbox placement by provider: See whether your emails land in the inbox, spam folder, or another tab across major mailbox providers.
• SPF, DKIM, and DMARC authentication: Verify that your email authentication records are configured correctly.
• Content quality signals: Identify content issues that may trigger spam filtering.
• Blacklist status: Check whether your domain or sending infrastructure appears on common email blacklists.
• Sender reputation indicators: Review factors that may influence how mailbox providers view your emails.
• Links and URLs: Detect broken, suspicious, or potentially problematic links within your email.

How it works

1. Send a test email

Start by sending an email to the addresses provided by the tool. Use the same sending platform, content, links, and settings you would use for a real campaign. Testing under real-world conditions produces the most accurate results.

2. We analyze your email

Our system evaluates inbox placement across major mailbox providers while checking authentication records, sender reputation signals, blacklist status, content quality, and links.

3. Review your report

You’ll receive a deliverability report showing where your emails landed and any issues affecting inbox placement. Use these insights to improve deliverability before launching your next campaign.

Who needs this?

Cold outreach teams

Even a well-written cold email won’t generate replies if it lands in spam. Use a deliverability test to identify inbox placement issues before launching outreach campaigns at scale.

Newsletter senders

Poor deliverability can hurt open rates and engagement, even when subscribers genuinely want to hear from you. Regular testing identifies problems before they affect campaign performance.

Agencies

Agencies managing multiple clients need visibility into deliverability across different domains, inbox providers, and sending platforms. Testing helps catch issues before they become client problems.

Recruiters

Whether you’re contacting candidates directly or running recruitment campaigns, inbox placement matters. A deliverability test can reveal authentication, reputation, or content issues that may prevent your messages from reaching qualified candidates.

Spam test vs. deliverability test

A spam test focuses on the email itself. It analyzes factors that may trigger spam filters, such as content, links, authentication records, HTML structure, and other technical signals. If you want to identify issues within a specific email before sending it, our Email Spam Test is the right place to start.

A deliverability test takes a broader view. Instead of only examining the email, it measures where the message actually lands across different mailbox providers. It shows whether your emails reach the inbox, spam folder, or another tab and highlights issues that may be affecting placement.

Think of it this way:

• A spam test asks: “Could this email trigger spam filters?”
• A deliverability test asks: “Where did this email actually land?”

For the best results, use a spam test to optimize individual emails and a deliverability test to monitor overall inbox placement and sender reputation over time.

Improve your inbox placement

Testing reveals deliverability problems. Fixing them requires consistent reputation building.
