Text and Email Marketing for Small Business: Setup, Rules and Campaigns to Run
How to set up text and email marketing the right way: A2P 10DLC, email authentication, consent rules, list tags, campaign ideas and copy-ready templates for service businesses.
By James Anderson · Updated · 10-minute read
The Short Answer
To run text and email marketing as a small business, set up the foundation first: register your business number for A2P 10DLC texting, authenticate your email domain with SPF, DKIM and DMARC, and collect clear consent with an easy opt-out. Then clean and tag your customer list, and send short, useful campaigns tied to real reasons: seasons, maintenance dates, finished jobs and offers for past customers. Use text for quick, timely messages and email for longer content.
Key Numbers at a Glance
US wireless carriers require A2P 10DLC registration for business texting from local 10-digit numbers.
Since February 2024, Google and Yahoo require bulk email senders to authenticate their domains, offer one-click unsubscribe and keep spam complaints low.
82%
of small business employers already use at least one automation tool (Verizon State of Small Business Survey, 2025).
Why Text and Email Still Win for Local Businesses
Social media reach rises and falls with the algorithm. Ads stop the day the budget does. Your customer list is the one marketing channel you own.
Past customers are the warmest audience a service business has. They know your work, trust your crew and already have your number. A well-timed text, "Time for your fall tune-up, book here," often books a job in minutes, with no ad spend.
The catch: texting and email have rules, and setup mistakes get messages blocked. Get the foundation right, and both channels work hard for years.
Text vs Email: When to Use Each
| Text (SMS) | ||
|---|---|---|
| Best for | Reminders, quick offers, seasonal nudges, booking links | Newsletters, photos, longer tips, detailed offers |
| Length | One or two sentences | A few short paragraphs |
| Speed | Seen within minutes | Read over hours or days |
| Frequency | Sparingly, a few times a month at most | Weekly or monthly |
| Setup needs | A2P 10DLC registration, consent, STOP handling | Domain authentication, unsubscribe link, physical address |
Most strong campaigns use both: a text to grab attention, an email with details.
Step 1: Register Your Business Texting
In the United States, business texts from local 10-digit numbers run through a carrier system called A2P 10DLC. Carriers require businesses to register their brand and describe each use case before sending.
What registration needs:
- Your legal business name and EIN, matching IRS records exactly
- Your website and business address
- A clear description of the messages you send
- Sample messages, including opt-out language
- How customers give consent
Tips for approval: Match every business detail exactly. Write specific sample messages. Show where customers opt in, such as a checkbox on your website form. Vague or mismatched submissions get rejected and delay launch by weeks.
Step 2: Authenticate Your Email Domain
Inbox providers check whether your email comes from the sender named. Since February 2024, Google and Yahoo require bulk senders to:
- Authenticate the domain with SPF and DKIM
- Publish a DMARC record
- Offer one-click unsubscribe
- Keep spam complaint rates low
Tips: Use a dedicated sending subdomain, such as mail.yourbusiness.com, to protect your main domain. Send a test to Gmail and Outlook before every new campaign type.
Step 3: Collect Consent the Right Way
- Add a consent checkbox to your website forms for marketing texts, unchecked by default, with plain language about what customers will receive
- Keep a record of when and how each person agreed
- Include opt-out instructions in texts ("Reply STOP to opt out")
- Honor STOP replies and unsubscribes right away
- Include your business name and physical address in marketing emails, as US CAN-SPAM rules require
Texting rules come from federal law, carrier policies and some state laws, including limits on texting hours in certain states. Rules change, so confirm current requirements with your attorney or platform.
Step 4: Clean and Tag Your List
Pull contacts from your phone, invoicing app, old spreadsheets and CRM into one place. Then:
- Remove duplicates and bad numbers
- Separate customers from leads, vendors and personal contacts
- Tag by service type: "AC install," "roof repair," "recurring cleaning"
- Tag by last job date and season
- Mark who has given marketing consent
Tags turn one blast into many small, relevant campaigns. A gutter cleaning reminder should reach homeowners who bought gutter cleaning, not everyone.
Step 5: Plan Campaigns Around Real Reasons
Every message needs a reason a customer would welcome:
- Seasonal: "Storm season is coming. Book a roof check."
- Maintenance: "Your water heater flush is due."
- Anniversary: "A year has passed since your new AC install. Time for a tune-up."
- Offer: "Past customers get first pick of our holiday light install dates."
- Helpful tip: "Three signs your gutters need attention before winter."
- Win-back: "We haven't seen you in a while. Here's 10% off your next visit."
Text Templates to Copy
"Hi [Name], [Business] here. Fall tune-ups are booking up. Grab your spot: [link]. Reply STOP to opt out."
"Hi [Name], your [service] is due this month. Pick a time here: [link]. Reply STOP to opt out."
"Hi [Name], as a past customer, you get first pick of [season] dates before we open them up. Book: [link]. Reply STOP to opt out."
"Hi [Name], [Your Name] from [Business] here. Long time no see! Anything around the house we should look at? Book here: [link]. Reply STOP to opt out."
Email Campaign Ideas
- Monthly newsletter: one tip, one recent job with photos, one offer
- Seasonal checklist: "Your fall home checklist," with a booking link for the items you handle
- Behind the scenes: meet the crew, a new truck, a community event
- Customer story: a before-and-after with the customer's permission
- Referral reminder: how your referral thank-you works
Keep emails short, with one clear button.
How Often to Send
- Texts: a few times a month at most to past customers, tied to clear reasons
- Email: weekly to monthly
- Watch opt-outs: a rising opt-out rate means too many messages or weak reasons
Common Mistakes
Texting from a personal cell to hundreds of people. Unregistered bulk texting gets blocked and risks your number.
Sending email from a free address. Bulk email from a free Gmail or Yahoo address struggles to reach inboxes.
Buying lists. Purchased lists break consent rules and wreck deliverability.
Same message to everyone. Use tags.
No call to action. Every message needs one clear next step, usually a booking link.
Forgetting replies. Customers reply to texts. Make sure replies land where someone sees them fast.
How to Measure Results
- Delivery rate for texts and inbox placement for email
- Click rate on booking links
- Replies and bookings per campaign
- Revenue from past customers each month
- Opt-out and spam complaint rates

Frequently Asked Questions
Is text message marketing legal for small businesses?
Yes, with clear written consent for marketing texts, opt-out instructions, quick handling of STOP replies, and A2P 10DLC registration for business texting from local numbers. Some states add rules, such as texting hour limits.
What is A2P 10DLC?
A2P 10DLC is the US carrier registration system for business texting from local 10-digit numbers. Businesses register their brand and message use cases. Unregistered traffic gets filtered or blocked.
Why do my marketing emails go to spam?
Common causes are an unauthenticated domain, missing one-click unsubscribe, sending from a free email address, and high complaint rates. Authenticate with SPF, DKIM and DMARC and send to people who opted in.
How often should a small business text customers?
A few times a month at most to past customers, each with a clear reason. Watch your opt-out rate and slow down if the rate climbs.
Should I use text or email marketing?
Both. Use text for short, timely nudges with a booking link. Use email for newsletters, photos and longer content.
Do I need a big list to start?
No. A few hundred past customers is enough for seasonal and maintenance campaigns, and small lists often get the best response.
Start with Your Past Customers
Your next job is likely sitting in your phone. Register your texting, authenticate your email, and send one seasonal message to past customers this month.
