Summary
Open rates of 70%, 100%, and 0% in test accounts provide varying insights into email campaign performance. A 70% rate can indicate strong engagement, but should be compared against industry benchmarks for context. A 100% open rate frequently points to issues within the testing setup like caching, automated opens, or whitelisting, and is not a reliable indication of real-world results. A 0% rate generally signifies deliverability problems, often due to spam filters, poor sender reputation, or failure to comply with email authentication standards (SPF, DKIM, DMARC). Factors like spam traps, similar testing environments, and bulk email guidelines also play a significant role in skewing data. Thus, test account open rates need cautious interpretation, consideration of industry benchmarks, and a focus on ensuring proper authentication and deliverability.
Key findings
- 70% Requires Context: A 70% open rate could be good, but needs comparison against industry benchmarks.
- 100% Often Skewed: A 100% open rate often indicates testing environment issues (caching, whitelisting).
- 0% Indicates Deliverability: A 0% open rate signals deliverability problems and potential spam filtering.
- Authentication is Key: Proper email authentication (SPF, DKIM, DMARC) is crucial for deliverability.
- Testing Environment: Test accounts are often not representative of subscriber behaviour.
- Spam Traps Affect: Spam traps influence high open rates in test accounts.
Key considerations
- Benchmark Data: Always compare test open rates with industry benchmarks.
- Validate Test Setup: Ensure testing setup accurately represents real-world conditions.
- Monitor Deliverability: Monitor deliverability metrics to identify and resolve issues.
- Email Authentication: Implement and validate proper email authentication (SPF, DKIM, DMARC).
- Compliance: Ensure compliance with bulk email sender guidelines.
- Metric Understanding: Thoroughly understand and analyse what the metrics really mean.
What email marketers say
9 marketer opinions
Open rates of 70%, 100%, and 0% on test accounts provide different insights into email campaign performance. A 70% open rate can indicate strong engagement, although industry benchmarks are needed for context. A 100% open rate often points to issues with the testing environment such as caching, automated opens, or whitelisted senders and is not representative of a typical campaign. A 0% open rate typically indicates deliverability issues, such as emails being blocked by spam filters. Factors such as similar devices, email clients, or being on the same network can skew results. Therefore, open rates on test accounts should be interpreted cautiously and in conjunction with real-world campaign data.
Key opinions
- 70% Open Rate: May indicate strong engagement but requires comparison to industry benchmarks for proper context.
- 100% Open Rate: Suggests issues with the testing setup, potentially due to caching, automated opens, or whitelisted senders.
- 0% Open Rate: Generally indicates deliverability problems, often because emails are being blocked by spam filters.
- Skewed Results: Similar devices, email clients, or being on the same network can distort open rate metrics on test accounts.
Key considerations
- Testing Environment: Ensure the testing environment accurately reflects real-world conditions to avoid skewed results.
- Industry Benchmarks: Compare test account open rates against industry benchmarks to assess performance.
- Deliverability Issues: Investigate sender reputation, authentication, and list hygiene if test accounts show a 0% open rate.
- Data Interpretation: Interpret test account open rates cautiously and in conjunction with real-world campaign data.
Marketer view
Email marketer from ActiveCampaign says that high rates on test accounts can be a reflection of the clients and devices used for testing. If your test accounts all use a similar email client and device, this could distort open rates.

Interpreting open rates of 70%, 100%, and 0% in test accounts requires careful consideration. While a high percentage *might* appear positive, experts emphasize understanding email metrics. It's crucial to compare these rates against industry benchmarks to gain context. Furthermore, inflated open rates can stem from factors like spam traps artificially inflating the numbers. Therefore, analyze these test open rates cautiously.
Key opinions
- High Open Rates Caution: High open rates in test accounts need careful interpretation and shouldn't be taken at face value.
- Context is Key: Compare open rates with industry benchmarks to understand their true meaning.
- Spam Traps: Spam traps can inflate open rates, skewing the data.
Key considerations
- Metric Understanding: A deep understanding of email metrics is necessary for accurate assessment.
- Benchmark Comparison: Always compare test results with relevant industry benchmarks.
- Data Validity: Be aware of factors like spam traps that can compromise data validity.
Expert view
Expert from Email Geeks shares that 70%/100%/0% is phenomenal. Then jokes why not open it on all 10 of the test accounts to get a perfect 100% open rate?

What the documentation says
4 technical articles
Email open rates in test accounts are significantly affected by server configurations, adherence to email standards, and spam filtering mechanisms. A 0% open rate often indicates deliverability issues arising from non-compliance with bulk email sender guidelines or aggressive spam filtering by services like Exchange Online Protection. Ensuring proper authentication (SPF, DKIM, DMARC) and monitoring deliverability metrics are crucial to prevent these issues. High open rates in test environments might not accurately reflect real-world deliverability due to permissive configurations.
Key findings
- SMTP Configuration: Incorrect SMTP server configurations can cause inconsistent deliverability, leading to blocked or spam-marked test emails.
- Bulk Email Guidelines: Failure to comply with bulk email sender guidelines (e.g., Google Support) can result in emails being filtered to spam.
- Aggressive Spam Filtering: Services like Microsoft's EOP can aggressively filter out suspected spam, resulting in low or zero open rates.
- Authentication Importance: Proper authentication (SPF, DKIM, DMARC) is crucial for avoiding deliverability issues and ensuring emails reach the inbox.
Key considerations
- Server Setup: Ensure proper server setup and adherence to email standards for consistent deliverability.
- Compliance: Comply with bulk email sender guidelines to avoid being flagged as spam.
- Authentication Protocols: Implement and maintain proper authentication protocols (SPF, DKIM, DMARC).
- Monitoring Deliverability: Monitor deliverability metrics to identify and address issues proactively.
Technical article
Documentation from Google Support details that bulk email senders must follow specific guidelines to ensure deliverability to Gmail accounts. Failure to comply can result in emails being filtered to spam or blocked entirely, resulting in a 0% open rate in some test scenarios.

Technical article
Documentation from SparkPost specifies that monitoring deliverability metrics and adhering to best practices such as proper authentication (SPF, DKIM, DMARC) is crucial for avoiding zero open rates. High open rates from tests may not accurately reflect deliverability for regular users.
