SMS vs email
How is SMS marketing different from email?
SMS arrives on a personal device, so it can feel more urgent and intrusive than email. Use it for short, expected messages where timing matters.
SMS has separate permission, carrier, registration, formatting, and pricing considerations. Requirements vary by country, sender type, provider, and message purpose.
Example / proof of SMS consent
A phone number is not permission.
A number may receive marketing SMS only when there is clear SMS consent, the local time is within allowed sending hours, the sender is registered where required, and the message explains who sent it and how to stop.
- RecordedConsent wording
- The exact statement shown when permission was requested.
- RecordedHow it was collected
- Where and how the permission was collected.
- ImmediateOpt-out
- A stop request removes the number from every campaign.
This sample shows what proof of consent a sender should keep. It does not belong to a real person.
Add SMS to a flow while keeping its stricter rules
Moosewave puts SMS and email steps in the same automated flow. Both can use the customer's activity history, but each keeps its own permission.
SMS permission stays separate from email permission. Moosewave checks quiet hours, opt-outs, character format, and estimated cost for each text step.
- SMS and email steps in one automated flow
- Separate SMS permission with its wording and time
- Automatic opt-out handling across marketing channels
- Quiet-hour checks using the recipient's local time
- Message parts, character format, and estimated cost shown before sending

ConsentWhat consent does SMS marketing require?
Marketing SMS often requires a clear opt-in specifically for text messages. Email permission or possession of a phone number may not be enough.
Requirements vary by location and use case. Record the wording, source, and time. Follow local rules for disclosures, opt-outs, quiet hours, and how long records must be kept.
- Express written consent
- A clear action agreeing to marketing texts. Whether it must be separate or written depends on the rules that apply.
- Double opt-in
- The subscriber confirms by replying or clicking. This creates a clearer permission record and can filter mistaken signups.
- STOP handling
- Recognising common opt-out replies and promptly preventing further marketing texts, as required by applicable rules and providers.
- Quiet hours
- Times when marketing texts should not be sent, based on the recipient's location and applicable rules.
- Sender registration
- Some countries and networks require a business to register its identity and intended messages before sending.
- Consent record
- The wording shown, time recorded, and page or channel where the person opted in.
Delivery failuresWhy do SMS messages fail to deliver?
Messages can fail because of an invalid number, missing registration, carrier filtering, blocked content, or account limits. The exact cause and remedy depend on the destination and provider.
Networks split texts into billable parts called segments. GSM-7 text can fit up to 160 characters in one part. Emoji and many non-Latin scripts use Unicode, which can reduce that to 70.
Channel fitWhen is SMS the right channel?
SMS suits short, expected, time-sensitive updates. Examples include delivery windows, appointment reminders, requested stock alerts, and one-time passcodes.
Use email or another channel for detailed explanations and product roundups. Before sending a text, ask whether the customer needs this message now.
Common questions
Can I send SMS to people who gave me their email address?
Do not assume email permission covers SMS. Obtain the permission required for text messages in each relevant location and keep a record of what the person requested.
How many characters is one SMS?
Networks split texts into billable parts called segments. GSM-7 text can fit 160 characters in one part. Unicode can reduce that to 70. Longer texts use several smaller parts.
How often should I send marketing SMS?
There is no universal schedule. Set expectations at signup, send only when the message is useful, and watch opt-outs and complaints as frequency changes.
Do I need to register my brand to send SMS?
It depends on the country, number type, network, provider, and use case. Check the destination-specific registration requirements before sending business messages.
Choose SMS only when it fits.
