Subject lines that get opens
Improve open rates with clear subjects.
Updated Feb 9, 2026
Overview
Email sequences work when the subject is clear and the body is skimmable with a single ask. Improve open rates with clear subjects.
Diagnostics
- Validate the email address and role.
- Confirm the location type is a good fit.
- Review any existing vending provider info.
Resolution steps
- Send a 3–5 email sequence with clear CTAs.
- Include a one-page PDF or short bullet list.
- Ask for a 10-minute call or quick walk-through.
Preventive maintenance
- Personalize the first line with location context.
- Avoid attachments if deliverability is poor.
- Use consistent follow-up spacing.
When to contact support
- Move to phone outreach after two opens without reply.
- Ask for the correct contact if you have the wrong person.
- Offer a short on-site demo.
See packages and pricing at /pricing. Start with leads at /vending-leads or /hot-leads.
Expanded guidance
- Confirm all steps are documented so the next technician can reproduce the results.
- Capture before/after metrics (errors cleared, sales restored, or uptime improved).
- Review machine, reader, or route settings to ensure they match location standards.
Common pitfalls
- Skipping a controlled test leads to false positives.
- Updating hardware without documenting configuration changes.
- Forgetting to verify payout, refund, or reconciliation data after changes.
Next-step checklist
- Run a final test with known-good inputs.
- Log the outcome with date, time, and device identifiers.
- Schedule a follow-up check if the location has high traffic or seasonal demand.
