April was less loud than March but quietly busier under the hood. Klaviyo kept turning itself into an agent. Shopify shipped a stack of features that should make daily store work a lot less stupid. Email deliverability got tighter again. SMS compliance changed.
Here's what actually matters, sorted by how urgent it is.
Do this now
Audit your SMS opt-out flow
Klaviyo's SMS opt-out compliance changes took effect April 11. Every SMS flow needs a working STOP response and clear opt-out language in the right places. This is a regulatory thing, not a Klaviyo thing. Klaviyo flagged it because non-compliance is what gets your sender number suspended.
If you haven't audited SMS flows since the start of the year, do it this week. Check the welcome flow, the abandoned cart, the post-purchase, the win-back. Look for STOP handling, opt-out language in the first message, and consent capture on the form.
Not glamorous. Necessary.
Use Meta Push Delivery the moment you have it
If you've ever added a new ad to a live campaign and watched it sit on near-zero spend while the old proven creatives eat the budget, Meta finally fixed it. Push Delivery is a toggle in the ad-level settings that forces a chosen percentage of your daily budget onto a specific new creative for up to seven days.
The detail that makes this matter: the ad keeps whatever learnings it accumulated when the push ends. No learning phase reset. This is what made testing creative inside main campaigns slow and risky for the last three years.
Rollout is phased. Roughly 5% of accounts already have it, 50% by May 25, 100% by July 10. Check the toggle the next time you build an ad. If it's not there yet, it will be soon.
One thing not to confuse: this is not Creative Testing. Creative Testing is for A/B comparison across variants. Push Delivery is for when you have one specific creative you want to be sure the algorithm actually reads. Different jobs, different tools.
Customize checkout by Market
Shopify's checkout and accounts editor now scopes changes to a specific market. Branding, settings, content blocks and copy can all vary per country, per region, or per custom segment like a B2B market. This means that customisations that used to require development can now be done by non-technical teams, such as:
- Only show payment methods popular in each market
- Country-specific shipping and return copy at the moment of decision.
- Local trust badges where they matter.
Available now on Advanced and Plus.
If you haven’t set up these localisation essentials, now is the time! Your conversion rate will thank you.
Get your email deliverability clean for 2026
Gmail and Yahoo tightened sender requirements again in Q1. The bar to land in the inbox keeps moving. The basics are non-negotiable now.
SPF, DKIM and DMARC properly authenticated. Spam complaint rate kept under 0.1%. Cold and unengaged subscribers separated from your engaged segments. A real sunset flow that actually removes people instead of moving them sideways.
We audit a lot of brands. Half of them still don't have this clean. If you sent a campaign last week and your open rate looked off, this is probably why.
Put it on your roadmap
Shopify Checkout Blocks: order value limits on every plan
Until April this was Plus only. Now everyone gets it. You can set minimum and maximum order values on discounts, free shipping, and other checkout rules.
Practical wins: stop BOGO abuse on small carts, cap free shipping at a cart value that makes margin sense, prevent discount stacking from going underwater. If you've been writing custom logic to do this, delete it.
Shopify B2B on non-Plus plans
Shopify made native B2B available on all plans at no extra cost. Until now, this was Plus only. The wholesale gate is gone.
What you actually get on non-Plus plans: company profiles for wholesale buyers, up to three custom catalogs with tailored pricing, volume discounts and quantity rules, vaulted credit cards, and payment terms.
Some of thes the heavier capabilities remain exclusive to Plus: unlimited catalogs, direct catalog assignment to companies and locations, partial payments, deposits.
This matters for any lifestyle brand running both DTC and wholesale on a workaround like using a b2b app, separate stores or manual order entry. Shopify's own numbers say merchants on B2B see up to a 33% lift in self-serve orders within six months and a 20% lift in reorder frequency. Start planning the migration.
Shopify finally gives you real testing tools: Rollouts and SimGym
Two features that arrived in the same month and belong together.
Rollouts schedules and stages storefront changes before pushing live. PDP redesign, new collection page, theme tweaks. Preview in production conditions, schedule the cutover, roll back if something breaks. This kills the 8pm launch panic. If your team has ever sat in a Slack huddle waiting to push a theme change, this is for you.
SimGym is the other half. A sandbox that runs simulated traffic against a proposed change, so you can see how it performs before any real shopper hits it. Useful for high-traffic launch days, BFCM staging, and catching the regressions that only show up under load.
Together, this is the first time Shopify has felt grown-up about pre-launch testing. I’d say Rollouts is a no-brainer, but I’d take SimGym with a pinch of salt for now.
Keep an eye on it
Shopify AI Toolkit, Claude and ChatGPT connectors
In April, Shopify shipped tooling that lets agents read and modify a live store. Real operations, not just analytics. Early and rough around the edges, but the direction is clear: routine store work moves from human hands to agent hands with human approval. Collection updates, product copy, theme tweaks, price changes - all managed in Claude Code.
Just a few days ago they made the barrier even lower: the Claude and ChatGPT connectors are here, which means you can just chat to Claude or ChatGPT, no need to use Claude Code and the terminal if you don’t feel comfortable with it.
Klaviyo is quietly becoming a customer ops layer
Easy to miss because it's been gradual. Next Best Product now runs in SMS, RCS and WhatsApp. Personalized onsite banners shipped. Customer Agent skills keep expanding into actual ecommerce decisions, not just message routing.
Klaviyo isn't an ESP anymore. It's becoming the layer that decides what each customer sees, gets, and is offered, across every channel. That changes how you should think about who owns lifecycle inside your team. And which other tools you might stop paying for in the next twelve months.
The bigger trend: AI is collapsing the stack
Zoom out from any single update this month and the pattern is clear. Klaviyo is becoming an agent layer. Shopify is becoming an operations layer. Composer, Customer Agent, AI Toolkit, Rollouts, agentic checkout. All from different vendors, all pointing the same direction.
The work is collapsing. Tasks that used to need a junior strategist, a copywriter, a developer and a campaign manager are now landing on one operator with the right tools. That doesn't mean fewer people. It means different people. The brands that figure out who actually needs to sit in the seat, and what tools belong in their hands, will move faster than the ones still hiring against an org chart from 2022.
That’s it for this month, stay focused and see you next month!
