August Retention Newsie

Welcome to The Retention Newsie by The Email Marketers - your biweekly dose of what's actually working in email and SMS retention for e-commerce brands. No fluff, no recycled 'best practices.' Just what we're seeing in the trenches with 50+ brands.

Let's get into it.

📉 Gmail quietly rebuilt its entire deliverability reporting system. Charts are gone. Plain-language verdicts are in. And one of them is basically Gmail calling your emails boring to your face.

☕️ A coffee brand just built the ultimate retention engine. 52 flavors in 52 weeks, a Guinness World Record attempt, and a subscription model that solves the "what do we even send this week?" problem most brands struggle with.

📱 iMessage is entering the e-commerce stack. Not SMS. Actual iMessage. One-on-one conversations between brands and customers with no spam folder, no carrier filtering, and open rates that make email look broken.

💸 Klaviyo SMS pricing overhaul hits today. Credits are dead. Dollar-based pricing is here. What to audit before your next billing cycle.

Google rebuilt the deliverability reporting inside Postmaster Tools in July, and they did it without announcing anything. No blog post, no press release. Practitioners spotted the changes by comparing dashboards and traced the underlying system to a Google API reference that had been sitting in developer preview since May.

The old view was charts. Spam rate over time, authentication pass rates, encryption percentages. You had to interpret what those lines meant for your sending reputation. The new view replaces interpretation with verdicts. Gmail now tells you, in a sentence, what it thinks of your email program.

Seven verdicts exist in the API, ranging from the one you want ("users signal they want to receive email messages") to the one that will ruin your morning ("users signal they don't want to get your email messages"). They sit on a spectrum: wanted, low engagement, not enough data, non-compliant, delivery errors, spam rate too high, and actively unwanted.

Three details matter more than the screenshots making the rounds on LinkedIn.

The 0.1% threshold is now an operational trigger, not an aspiration. Since the 2024 sender requirements, Google's public guidance has been "keep spam complaints under 0.1% and never let them reach 0.3%." For two years, 0.1% functioned as a nice goal. The gap between 0.1% and 0.3% was a grey zone where a lot of senders quietly sat, compliant enough to avoid the cliff. The new verdict system fires the SPAM_RATE_HIGH warning at 0.1%. A sender running at 0.25% who previously had no signal telling them anything was wrong now gets flagged. The aspirational number became an operational one.

Indifference is now a named condition. This is the change with the most long-term impact. The verdict USER_FEEDBACK_LOW exists for senders whose recipients neither complain nor engage. They don't open. They don't click. They don't reply. They just receive and ignore. Previously this group was invisible in deliverability reporting because they generate no negative signal in the traditional sense. Now Gmail tracks it as a distinct negative outcome, one step below "users don't want your mail." Deliverability practitioners have argued for years that engagement matters and been told by their own clients that it's folklore. Here it is as an enum in Google's API.

Google is verifying behavior, not just headers. The compliance checks now include eleven requirements as binary pass/fail: SPF, DKIM, both together, DMARC policy, DMARC alignment, RFC 5322 formatting, forward and reverse DNS, TLS, spam rate, one-click unsubscribe, and whether unsubscribes are actually honored. That last one is the kicker. Google is checking whether you actually stop emailing people who unsubscribe, not just whether you have the button.

What this means practically for e-commerce:

• Your ESP dashboard won't show this. These verdicts live in Postmaster Tools, tied to your sending domain, not your Klaviyo or Mailchimp account. A domain can accumulate a negative verdict while every metric inside the ESP looks fine. If you haven't logged into Postmaster Tools recently, do it this week.

• Your engaged segment is your real list now. Send to subscribers who have opened or clicked in the last 90 days and target 60%+ open rates on that segment. Everyone outside that window is contributing to the indifference verdict whether they complain or not. Gmail treats a large quiet audience as a sending problem, not a missed opportunity.

• Subject line tricks are dead. AI models (Gmail's Gemini, Apple Intelligence) now sit between your send and your subscriber's inbox, evaluating whether the content matches the subject line. Semantic drift between a clickbait subject and the actual email content gets detected and flagged.

• Run a sunset flow. Now. Suppress non-engagers who haven't opened in 180 days. Yes, your list will shrink. Yes, your deliverability for the subscribers who actually want to hear from you will improve. The brands that win in Q4 will be the ones who cleaned their lists in August.

Java Factory is releasing a new limited-edition coffee flavor every single week for a year. They're going for a Guinness World Record. The flavors have names like "Grandma's Candies," "Saturday Morning Cartoons," and "I Love Rocky Road." The whole thing is organized into six themed seasons (Throwbacks, Ice Cream Truck, Sweater Weather, Wild Ones, Just Desserts, The Finale), each with its own identity.

On the surface it looks like a PR stunt. It's not. It's one of the most structurally sound retention plays we've seen this year.

The subscription model solves the biggest retention problem in DTC. You can buy by season or buy the full VIP pass ($399 for all 52 flavors, 624 pods, 12 monthly deliveries). This isn't a "subscribe and save 15%" play where the customer forgets what they signed up for. Every monthly delivery contains four new flavors the customer has never tried. The product itself is the reason to stay subscribed.

52 weekly drops = 52 reasons to send an email. Most e-commerce brands struggle with send frequency because they run out of things to say. Java Factory built the content calendar into the product. Every Monday is a new flavor reveal. Every Friday they run a #FlavorFriday community event where subscribers brew and post reactions together. That's 104 natural touchpoints in a year before you even count abandoned cart flows or review requests.

They turned customers into participants. Subscribers vote on which flavors become permanent. They get collectible mugs, secret hot chocolate flavors that aren't sold separately, and a playing card deck with all 52 flavors. This isn't consumption. It's membership. The VIP tier includes a sweepstakes for an NYC trip to the Guinness World Record reveal at the Fancy Food Show.

The insight for retention marketers: Java Factory didn't ask "how do we get customers to buy more coffee?" They asked "how do we give customers a reason to come back every week?" Those are fundamentally different questions, and the second one produces fundamentally better retention.

Most brands try to solve churn with discounts or loyalty points. Java Factory solved it with anticipation. The next flavor is always seven days away. You can't get it anywhere else. And if you leave, you miss the story.

If you sell a consumable product and you're struggling with subscription churn, study this model. The answer might not be better pricing or more flexible subscription management. It might be making the subscription itself the product.

There's a tool called Intellica that enables actual iMessage conversations between DTC brands and their customers. Not SMS. Not RCS. Native iMessage, the blue bubble, with read receipts and the trust that comes with a message from a real person.

Cozy Earth and Jack Archer are already using it. The model is fundamentally different from any SMS platform: US-based human concierges, trained in the brand's voice, who step in at checkout to answer objections, recover abandoned carts, and build one-on-one relationships that compound into LTV.

Why this matters: SMS as a retention channel has a trust problem. Consumers increasingly treat branded SMS like spam. Carrier filtering catches legitimate messages. Open rates are still strong relative to email, but the conversion gap is narrowing because the channel itself feels transactional. "Hey {first_name}, your cart is waiting!" stopped working a while ago.

iMessage changes three things at once:

Trust. An iMessage from a brand feels like a text from a friend, not a marketing blast. There's no short code, no "reply STOP to unsubscribe" footer, no carrier filtering. For iPhone users (which, in premium DTC, is most of your customer base), the blue bubble carries implicit trust that green-bubble SMS does not.

Two-way conversation. Most SMS tools were built to broadcast. Intellica was built to listen. When a customer responds to an abandoned cart message, a human answers. They uncover shipping objections, payment issues, product questions, and competitor concerns in real time. One brand discovered a broken AMEX integration during BFCM through conversations that would have been invisible in a traditional flow.

Product intelligence. Because real people are having real conversations, brands get qualitative data that no analytics dashboard captures. Product requests, persona insights, competitor mentions, sizing confusion. Jack Archer got a golf wear product insight from customer conversations that they turned into a new product line.

The pricing model is pure performance: 10% commission on purchases attributed within 24 hours, no setup fees, no contracts. If a customer buys later on their own, the brand keeps 100%.

We're not saying iMessage replaces SMS or email. But the retention stack just got a new layer, and the brands paying attention to it now will have an advantage when it scales.

Klaviyo is moving SMS from credit-based to dollar-based pricing, effective your first billing cycle after August 13. If you're running SMS through Klaviyo, this affects your next invoice.

The short version:

• Credits are gone. You'll pay per-message rates in actual dollars, broken out by toll-free vs. short code and by region.
• Over 70 new plan tiers replace the old one-size model. Some brands will pay less, some will pay more. It depends on your channel mix and volume.
• Rates haven't changed since 2022. This update reflects current carrier fees.

What to do before your next billing cycle:

1. Pull your SMS sending breakdown by channel type (toll-free vs. short code) and region.
2. Map your current credit usage to the new dollar-based rates to see where you land.
3. If you're heavy on toll-free US sends, you'll likely come out ahead. Heavy international or short-code senders should model the new pricing carefully.

🛒 Agentic commerce is here. Shopify published on AI agents (ChatGPT, Google's AI Mode, Copilot) helping consumers browse and buy. Shopify merchants can now sell through AI agent interfaces. The question for retention marketers: how do you build a relationship with a customer acquired by a robot? Your post-purchase sequence just became the first human touchpoint.

📊 August benchmarks (Attentive). Email retail/ecomm: 13.11% CTR, 10.10% CVR, $4.37 rev/send. SMS retail/ecomm: 8.02% CTR, 22.48% CVR, $4.14 rev/send. The number that jumps out: SMS conversion rates are crushing email across every vertical, especially F&B where SMS hits a 34.14% CVR. August is the last clean month before BFCM planning takes over. Use it to audit.
