Part of Email Marketing Runs on Permission Before It Runs on Automation
How a B2B Manufacturer and Bake Club Used Email Differently
Small business email marketing case studies examine a B2B manufacturer and Bake Club, separating useful operating choices from vendor claims and open-rate limits.
What to take away
- Both stories earn one read each, for the operating choices only. Constant Contact published both, so every percentage is a claim rather than evidence.
- Dai Phuc Hung Thinh feeds a slow B2B sale with a weekly education email and invitation-only signups.
- Bake Club grows a recipe community by segmenting subscribers and testing on a small active group first.
- Neither story publishes list size, send dates, open-counting rules or revenue per subscriber, so no reported rate can be checked or copied.
- Copy one tactic, run it on a bounded segment, and judge it on replies, opt-outs and net list growth.
Verdict: useful for structure, weak for proof
The B2B story is dated November 2025 and sits on Constant Contact's own site. The Bake Club story ran in 2025, in the same place. Both describe named customers doing real work. Both are also marketing for the software vendor.
Each is worth one read. The value is in the mechanics rather than the results. Both cases lean on permission, a stated promise and a cadence the sender can keep, which is the ground covered in business email marketing beyond tool choice.
What neither supplies is a baseline. Without list size, send date and a defined measurement window, an open rate is a number with no denominator. That leaves you nothing to compare against your own list.
Dai Phuc Hung Thinh: weekly education for a slow sale
The story names William Mai, a Constant Contact employee, marketing his family's outdoor furniture manufacturing business in his spare time. He builds the list by invitation rather than buying or scraping contacts.
His routine is steady:
- Prospect research before any invite
- Invitation-only newsletter signup
- One industry education send each week
- Replies answered by the owner
- Blog posts reused as email content
The story reports open rates it describes as high. It gives no list size, no send dates and no definition of how an open is counted. Mai's job at the provider is a material connection, and a reader should weigh it.
Bake Club: recipes, segmentation and a test group
Bake Club is a recipe-led community email that sends subscriber-only recipes every week. The story does not state its subscriber count, revenue or staff size, so read it as a small community operation rather than a scaled brand. For permission-aware signup flows the case does not spell out, small business email marketing examples is the better starting point.
Signup is promoted through owned and social touchpoints. The team separates contacts by activity and interest, runs a small active group before wider sends, and later automated the segmentation.
The story reports year-over-year movement in list size and open rates, plus hands-on support from Constant Contact's team. Vendor staff help and vendor case selection both argue for discounting the size of any lift.
What the published figures will and will not carry
| Reported in the story | Left out | What you can measure instead |
|---|---|---|
| High open rates for the B2B newsletter | List size, send dates, open-counting rules | Your open rate before and after one change |
| Year-over-year list and open-rate movement at Bake Club | Starting size, churn, unsubscribe rate | Net list growth after opt-outs |
| Weekly sends and behavior-based segmentation | Revenue per subscriber, staff hours | Replies and hours per 100 sends |

A published open rate is an objective advertising claim. The FTC advertising substantiation policy requires a reasonable basis before such a claim is disseminated. That duty falls on the advertiser, and it is a fair test for any case study you plan to repeat in your own materials.
Typical small business email open rates sit in the 20 to 40 percent range. Treat that as a typical range, not a target. The comparison that matters is your list against its own past, and small business email marketing benchmarks explains which parts of a published baseline are worth trusting.
Consent rules travel with the recipient. If you email Canadian addresses, the CASL guidance from Innovation, Science and Economic Development Canada covers express and implied consent, sender identification and unsubscribe handling.
Quoting a customer's result carries its own risk. The FTC guidance on reviews and endorsements warns about hidden relationships, selective requests and incentive conditions.
Test one tactic on a segment you can afford to lose
- Choose one tacticthe invited weekly education send, or the active-group test before a wider send.
- Carve out a few hundred contacts you can afford to lose, and hold everything else steady.
- Write the promise in one sentence and put it on the signup form.
- Send on a fixed schedule for four to six weeks.
- Record replies, opt-outs, complaints and net list growth every week.
- Stop if complaints or opt-outs climb, and keep the change only if replies or repeat opens improve.
Use the small business email marketing checklist to catch the collection and permission steps that both case studies pass over quickly.
Common questions
Do these Constant Contact stories prove the tool works?
No. They are vendor-published examples with no disclosed starting point. Test fit with a controlled send to a small slice of your own list.
Which lesson transfers most easily?
Define why a specific group should expect your email, keep that promise weekly, and answer replies yourself. That holds whether you sell furniture or recipes.
Can I copy Bake Club's segmentation now?
Partly. Splitting contacts by activity is cheap once your tool supports it. The test group only pays off if you change what you send based on what it shows.
What happens if I quote these numbers in my own marketing?
You take on the substantiation duty. A vendor story is not a reasonable basis for an objective performance claim about your business.
