An email is transactional when its primary purpose is to complete or confirm a transaction the recipient already started (order confirmation, password reset, shipping notice). It is marketing when the primary purpose is promotional. Pure transactional messages generally do not require marketing consent or an unsubscribe link; promotional ones do. Mixing significant promotional content into a receipt can flip the classification under the primary-purpose test.
The Primary Purpose Test
Ask what the message exists to do. If it facilitates, completes, or confirms a transaction the user already agreed to, or delivers account/security information tied to that relationship, it is transactional. If it advertises or promotes products or services as its main goal, it is commercial/marketing. When content is mixed, US CAN-SPAM rules look at the subject line and whether substantial transactional content appears at the beginning of the body. Significant upsell in a receipt often makes the message commercial.
Consent and Unsubscribe Rules by Type
| Type | Typical triggers | Consent needed? | Unsubscribe required? |
|---|---|---|---|
| Transactional | Order confirm, password reset, shipping, account alert | No (contractual/relationship) | Generally no under CAN-SPAM |
| Marketing / commercial | Newsletter, sale, product promo | Yes (opt-in or soft opt-in depending on jurisdiction) | Yes, working opt-out |
| Mixed (receipt + strong upsell) | Receipt with dominant promotional content | Often treated as commercial | Yes |
These are high-level distinctions, not legal advice. Verify current rules for your jurisdictions (CAN-SPAM in the US, GDPR/PECR in the EU, CASL in Canada).
Jurisdiction Notes
- US CAN-SPAM: pure transactional/relationship messages are largely exempt from unsubscribe and postal-address requirements if the primary purpose is transactional. Commercial messages need a working opt-out. Primary-purpose test applies to mixed content.
- EU GDPR / PECR and Canadian CASL: pure transactional messages often rely on contractual necessity or similar exemptions. Marketing requires consent (or limited soft opt-in). Adding significant promotional content can change the legal basis.
- Google/Yahoo bulk-sender rules focus on authentication and one-click unsubscribe for bulk commercial/marketing mail. Do not apply marketing unsubscribe requirements blindly to pure transactional messages.
How We Analyzed This
We reviewed the FTC CAN-SPAM primary-purpose criteria (16 CFR 316.3), standard distinctions used by major inbox providers for bulk commercial mail, and ArawaMail documentation. ArawaMail is built for company domains, hosted mailboxes, and HTTP API / library sending of transactional volume. Arawa Mail plans include a monthly transactional-email allowance, and the docs describe no marketing-campaign or list-management tools.
Sending Both From ArawaMail
You can send transactional messages through the ArawaMail API or mailboxes on your domain. Marketing volume and consent management sit outside the documented product scope. If you later run high-volume marketing, consider separate subdomains for reputation isolation and apply the matching consent and unsubscribe practices.

FAQ
Does a pure receipt or password-reset email need an unsubscribe link?
Under CAN-SPAM, if the primary purpose is transactional, generally no. Adding substantial promotional content can change that.
What happens if I add product recommendations to a receipt?
If the promotional content becomes significant or the subject line reads as promotional, the message is likely treated as commercial and needs the corresponding consent and opt-out practices.
Can I send both transactional and marketing from the same ArawaMail domain?
Technically yes for transactional volume, but ArawaMail is positioned for transactional/API sending plus mailboxes, not as a marketing platform. Separate subdomains help protect reputation if marketing volume grows.
Is this legal advice?
No. Rules vary by jurisdiction and change. Confirm current requirements with qualified counsel for your use case.
