Klaviyo vs. Marketing: Which is better for email campaigns?

Topic summary

Main issue: Klaviyo fails to sync new subscribers added via Shopify POS, so the automated Welcome Series (“flow” = a sequence of scheduled emails) doesn’t trigger. Separately, many emails land in recipients’ spam/junk when sent via either Klaviyo or Shopify Marketing.

Deliverability status: Klaviyo support adjusted the domain configuration, but additional steps with the email provider are still needed to fully resolve spam placement.

Platform considerations: Shopify Marketing appears to offer similar automations/flows and may be simpler. The poster asks if there’s a compelling reason to keep using Klaviyo versus relying on Shopify’s native automations.

Responses: One participant requested more details and later proposed a call to discuss and possibly recommend an alternative app. No technical fixes or comparisons were provided in-thread.

Key terms: Klaviyo (email marketing automation platform). Shopify POS (point-of-sale system for in-person sales). Welcome Series/flows (automated email sequences for new subscribers).

Outcome & status: No resolution yet. Action items include completing email provider steps for deliverability and potentially discussing alternative tools via a call. Discussion remains open.

Hello everyone,

I’ve been running an online and box sporting good’s store for almost a year now. I’ve used both Klaviyo and Shopify Marketing to run (some) campaigns and automated flows.

I’ve had a lot of issues with Klaviyo and having it sync new contacts when they are added via Shopify POS resulting in them not receiving a Welcome Series for subscribing.

I’ve also ran into the issues of having most of my e-mails going into the junk or spam folders of my recipients through either platform when I manually send out the welcome e-mail among others as well.

Is there much reason to use Klaviyo still as Shopify seems to offer a lot more when it comes to e-mail marketing?

Or have you ran into similar issues like myself while using the Shopify’s POS system and Klaviyo flows?

Thank you.

Schuyler

Hello Ketan and thank you for replying.

The majority of my issues with Klaviyo are when I use my Shopify POS system to add a new subscriber, Klaviyo seems to skip on sending them the welcome series flow e-mail or rather just doesn’t even acknowledge them at all. They will just go into the Newsletter segment and nothing else will come from it. I could just manually send them the e-mail but that just defeats the purpose of the flow in the first place.

Another issue I am having is the fact my e-mails when used with Klaviyo, they apparently go right to spam folders and I had Klaviyo support go in and fix the domain but there are a few steps yet with my e-mail provider I need to take in order to fully resolve that issue.

Shopify’s Marketing seems to have most of the flows that I would be operating under Klaviyo and might not cause this many issues already…

Is there much of a reason to not utilize the Shopify provided automations and marketing over Klaviyo and others out there?

I just simply want to be able to add my customers and have the flows and automations work properly,

Thank you
