The four rules
-
Sound like a person, not a brand — 'Quick question about your roof' beats 'Roofing services in Houston'
-
No emoji in the first line of a B2B sequence — emoji read as marketing; we are aiming for personal
-
Promise one specific thing — 'Three numbers to watch this quarter' beats 'Marketing tips for your business'
What to test
- Subject A vs B over the same send-time window, 500+ recipients per arm
- Open rate as the headline metric; reply rate as the truth-teller
- One change per test. Two changes and you cannot tell which one moved the needle.
Examples that have worked for our Houston clients
These are patterns, not magic words. Adapt to your voice.
- 'Quick question about [their business]'
- 'Three things I noticed about [neighborhood] last month'
- 'Worth ten minutes?'
- 'Two minutes — your weekend forecast'
- '[First name], is this still right?'
What to avoid
- ALL CAPS subject lines
- 'Re:' or 'Fwd:' prefixes on cold sends — looks deceptive, hurts deliverability
- Multiple exclamation marks
- Anything that sounds like an ad
Where BayouEdge helps
We write subject lines as part of every email engagement. James drafts; you approve. We log which lines won and feed that back into the next campaign.

Frequently asked questions
What is a realistic open rate for a Houston small business email?
30-45% for nurture sequences to engaged lists. 15-25% for cold or dormant lists. Anything below those bands is a subject line or deliverability problem.
Does personalization in the subject line help?
First-name personalization adds 5-10% open rate when done well; less when overdone. Beyond first name, personalization in the subject line reads forced and reduces opens.
Should I A/B test every send?
Test the first three sends in any new sequence. Once the cadence settles, test once a quarter to keep the data fresh. Continuous testing on every send burns the list.
Do emoji help or hurt?
Hurt for B2B and most service-business sends. Help for B2C lifestyle and retail. Houston small businesses we work with skip them by default.
