This is one of the best SMS and call apps I have encountered so far. It integrates with ActiveCampaign and also lets me record calls. The call quality is great and the setup is easy. The customer support is great and new features are added all the time.

“Boosted webinar attendance to 90%
Salesmsg is just what we need to build the relationships with our clients. We had another campaign we did using SMS - an offline seminar meeting, where 90% of attendees confirmed that they showed up only because they got the SMS reminders.

“72% increase in outreach engagement
We were limited to emails and leaving voicemails when a client was unavailable to answer the phone. The advantage Salesmsg gives us is quicker response times and an all-inclusive contact strategy increasing our outreach engagement by 72%!

Salesmsg + Klaviyo Integration FAQs

Looking for more information about the Salesmsg and Klaviyo integration? We've shared some answers below to get you on your way efficiently and effectively! Got More Questions? Text “ASK” to (888) 409-2298

How does the Klaviyo integration with Salesmsg work?

Salesmsg provides a native webhook URL that you drop into any Klaviyo flow. When the flow fires, Klaviyo sends the event to Salesmsg, and Salesmsg sends an SMS to the phone number in the profile. No middleware required.

Do I need Zapier or Make to connect Klaviyo and Salesmsg?

No. This is a direct webhook integration. You paste the Salesmsg webhook URL into Klaviyo's webhook action and you're live.

Does this replace Klaviyo's own SMS marketing feature?

No. Klaviyo's SMS marketing is a separate, broadcast-style feature Klaviyo sells directly. It has nothing to do with this webhook. Salesmsg is what actually sends the SMS triggered by your Klaviyo flow, and it adds the two-way reply and calling that Klaviyo's own SMS marketing doesn't do.

What Klaviyo events can trigger an SMS?

Any event that can trigger a Klaviyo flow. New subscriber, abandoned checkout, back-in-stock, browse abandonment, and purchase confirmation, verified against Klaviyo's own flow trigger list.

Can I personalize the SMS with data from Klaviyo?
Does this work with my existing Salesmsg phone number?

Yes. Every SMS this integration sends, triggered messages and replies, goes out from the Salesmsg number you already use.

Is this integration TCPA-compliant?

Salesmsg handles TCPA compliance, opt-outs, and 10DLC registration on our side. You still need to make sure your Klaviyo list has SMS consent.
