Test Sending Best Practices#
To ensure reliable test delivery:
- Use Real Mailboxes: Test on real accounts across different domains (@gmail.com, @outlook.com, @icloud.com, and corporate Google Workspace).
- Check Spam Filters: If a test email lands in spam, check your subject line for all-caps words or verify that external image URLs are using secure HTTPS.
- Prefix Subject Lines: PostBrix automatically prefixes test email subjects with
[TEST]to avoid confusing stakeholders.
Frequently Asked Questions
Why did my test email land in the Gmail Spam folder?
Test emails sent from development servers without domain DKIM alignment often trigger spam filters. Whitelist the test sender or export HTML to send test proofs directly from your authenticated ESP.
Can I send test emails to multiple colleagues at once?
Yes. Enter up to 5 comma-separated email addresses in the test dialog to review drafts collaboratively.
