Email deliverability
Email deliverability for regulated brands in Klaviyo
Because SMS is so constrained for regulated brands, email often becomes the workhorse retention channel - if you set it up right. Here is how to protect deliverability in Klaviyo, and where its SMS product stops short.
This is practical operator guidance, not legal advice. Platform policies change - verify current Klaviyo terms for your category before you build.
Why email matters more for regulated brands
Because SMS is so restricted for cannabis, firearms, vape, and similar categories, email frequently becomes the most reliable retention channel a regulated brand has. That makes deliverability - landing in the inbox rather than the spam folder - a direct revenue issue, not a technical afterthought.
Get authentication right first
- Set up SPF, DKIM, and a DMARC policy on a dedicated sending domain or subdomain.
- Authenticate before you scale volume - mailbox providers distrust unauthenticated mail.
Note
Authentication is table stakes. After Google and Yahoo tightened bulk-sender requirements, unauthenticated senders see real deliverability damage. This is the first thing to fix, not the last.
List hygiene and engagement
- Send primarily to engaged subscribers, not your entire list every time.
- Suspend or sunset chronically unengaged profiles instead of mailing them forever.
- Remove hard bounces and spam complaints quickly.
- Never buy or import cold lists.
- Warm new domains and higher volumes gradually.
Mailbox providers reward engagement. Blasting your whole list every send tanks sender reputation and quietly pushes more of your mail to spam over time.
Segmentation and flows that protect reputation
- Run the core flows: welcome, browse and cart abandonment, post-purchase, winback, and sunset.
- Segment by engagement and purchase behavior, not just by who is on the list.
- Throttle toward deliverability and revenue, not vanity reach.
The Klaviyo SMS catch for regulated brands
Klaviyo is excellent for email, but its SMS product does not support restricted or prohibited goods. Cannabis, CBD, and other SHAFT-adjacent categories are generally not allowed on Klaviyo SMS, which catches a lot of regulated operators by surprise.
Important
Plan a multi-platform channel mix. A common pattern is Klaviyo for email and a compliance-built platform like Alpine IQ or Springbig for the limited compliant SMS and loyalty messaging that is viable. Do not assume one tool covers every channel.
Where CapraCX fits
CapraCX helps regulated brands get Klaviyo authentication, segmentation, and flows right - and design a channel mix that respects where each tool can legally and reliably operate.
Key takeaways
FAQ
Common questions
Can I use Klaviyo for a cannabis or CBD brand?
You can use Klaviyo email for many regulated brands, but its SMS product generally prohibits cannabis, CBD, and other restricted goods. Confirm the current policy and plan SMS through a compliance-built platform.
What hurts email deliverability most?
Missing authentication, sending to unengaged or purchased lists, ignoring bounces and complaints, and sudden volume spikes without warming are the usual culprits.
Do I need a dedicated sending domain?
For serious senders, a properly authenticated dedicated domain or subdomain is strongly recommended. It protects your reputation and supports a DMARC policy.
Is email better than SMS for regulated brands?
Often yes, simply because SMS is so restricted for these categories. A strong email program plus compliant channels usually beats fighting carrier filters with SMS.
