Has anyone integrated a CRM with Klaviyo that allows them to see customer responses to email and SMS messages and the resulting conversations with them?

Right now we are juggling SMS responses thru Helpdesk with mail responses in a unified but separate email box and 800 number forwarding to our system. We are not able to have a central point of truth for all customer interactions.

We are not ecommerce and our lead responses are high value (avg $4500) so each customer interaction is very importatnt.

Has anyone implemented an integration that combined two or all three of the response channels?

Any help would be greatly appreciated.

Hi ​@ptrau , 
I have run into this exact situation before, especially with service based businesses where each lead is high value and missing one conversation can cost real money. The mistake many teams make is trying to force everything into one platform but what actually works better is making sure evey response.. email, SMS, or phone gets logged back into one customer record automatically. 
In one setup I handled, we kept Klaviyo for messaging, used the CRM as the main record, and connected the phone system so every call and reply showed up on the same timeline. That way, when a rep opened a contact, they could immediately see the full history, the emails, texts and call without checking three different plaves.

The turning point was using a connector workflow to push responses into the CRM as activities. Once that was in place, follow ups became easier, duplicates reduced, and the team stopped missing conversations. It's also made reporting clearer because management could see exactly which interaction moved a lead forward.
Since you are not e-commerce and you average lead is around $4,500 visibility and speed matter more than fancy automation. What you are really looking for is a single timeline of interactions not necessarily a single tool. This works well if it's well mapped , if you are comfortable sharing which CRM and phone provider you are using, it would be easier to suggest the most reliable connection path without overcomplicating things!!

I hope you find this helpful!

Thank you for the detailed response. It serves as reinforcement for the path we are considering to take. We are testing the tech stack of Klaviyo - CRM (Hubspot or equal) - Telephony (JustCall/SalesMsg/etc). We can natively integrate these without middleware (Zaps) and have a single source of truth in the CRM. This will give us the needed visibility to engage and close the warm inbound multi-channel responses we get.

We will still rely on API/Power Queries to build pivots and reports on customer activities as they progress through the Klaviyo Flows and Campaigns.

Will report back when we find what ROI the new stack delivers.

 

Thanks again for the thoughtful reply.
