100 distinct lines
Each collection contains ten real campaign categories with ten unique subject-and-preview pairs in each.
Curated subject-line library
Email Subject Lines by Industry
Browse 400 curated email subject lines with matching preview text for dentists, real estate agents, restaurants, and ecommerce brands.
Four curated collections are live now. Seasonal examples are filters inside each collection, so every indexed page remains substantial and useful year-round.
Made for real email jobs
Industry context changes what a useful subject line sounds like.
A dental recall, an open house, a seasonal menu, and a back-in-stock email should not sound like the same template with one noun replaced.
These collections start with the actual messages each industry sends. Every subject is paired with preview text, grouped by campaign, and tagged by tone and season.
Start with the closest collection, filter to the job at hand, and adapt the line so it accurately matches the email readers will open.

The editorial standard
Useful before it is searchable.
Visible without JavaScript
The complete library is in the page. Filters make it faster to use but do not hide the content from people or crawlers.
No fake urgency
The lines avoid deceptive replies, invented deadlines, unsupported outcomes, and all-caps pressure.
Season inside context
Seasonal examples live beside evergreen campaigns until a seasonal topic deserves a genuinely deeper standalone resource.
A simple workflow
Pick the real campaign
Start with the email's job: remind, educate, welcome, launch, reactivate, or invite.
Match the promise
Choose a subject that the body of the email actually delivers. Specific beats mysterious.
Use the preview
Let preview text add a second useful detail instead of repeating the subject line.
Apply judgment
Check accuracy, privacy, dates, availability, and the expectations the wording creates.
