Amazon's Free Email Channel. Most Brands Aren't Sending It.

What MYCE is and how to access it

MYCE is Amazon's first-party email channel for Brand Registry sellers. Understanding what it is and what it is not tells you why it deserves a place in your weekly operating rhythm.

The platform definition

Manage Your Customer Engagement (MYCE) is a free email campaign tool inside Seller Central accessible only to Brand Registry brands. Sellers compose email campaigns using Amazon's pre-built templates, select a customer segment, and send. Amazon delivers the email to the segment's mailbox addresses, handles deliverability, and reports back aggregated performance metrics (opens, clicks, attributed orders).

Access path inside Seller Central

Login to Seller Central. Navigate to the Brands menu (top navigation, requires Brand Registry). Select "Manage Your Customer Engagement" from the dropdown. The dashboard shows your customer audience sizes across all five segments, recent campaign performance, and a "Create New Campaign" button.

What MYCE is not

• Not an email service provider — you cannot export the list, integrate with Klaviyo or Mailchimp, or BYOL (bring your own list)
• Not a transactional email tool — order confirmations, shipping updates, returns go through Amazon's standard customer messaging
• Not a customer service channel — replies to MYCE emails do not route back to the brand directly
• Not a paid feature — no subscription, no per-email cost, no usage tier

The Brand Registry requirement

MYCE is locked behind active Brand Registry status. Resellers, distributors, and third-party sellers operating without Brand Registry cannot access the tool. This single-brand limitation is intentional — Amazon wants the brand-to-customer relationship gated through verified brand entities to prevent spam.

The 5 customer segments

Amazon expanded MYCE segmentation through 2024-2026 from a single "Brand Followers" audience to five distinct segments. The right segment for the right campaign is the highest-leverage decision in MYCE program design.

The segment-to-campaign matching rule

Each segment performs best with specific campaign types. Mismatched pairings waste sends and risk unsubscribes. The matching: All Followers for big announcements; Recent Customers for product launches; High-Spend for VIP and premium; Repeat for cross-sell; Cart Abandoners for deal-driven recovery only.

The All-Followers temptation

The largest segment is the most tempting to send to every campaign. Resist this. Sending every campaign to All Brand Followers burns out the broad audience, drops open rates over time, and produces unsubscribes from people who joined to follow occasional updates — not weekly emails. Use All Followers selectively for genuinely brand-wide moments.

The 6 campaign content types

Six content types perform consistently in MYCE. Most brands rotate through 3-4 of these across a 90-day cycle. The mix depends on product launch cadence, deal frequency, and brand storytelling resources.

Type 1: New product launch

Announcement of a new SKU or variant. Best segment: Recent Customers or All Followers depending on launch scale. The launch email is the workhorse format for brands with regular new product flow. Hero image of the new product, 1-2 sentences of positioning, single CTA to the new ASIN.

Type 2: Restock alert

Notification that a previously out-of-stock SKU is back. Best segment: Cart Abandoners on that SKU (highest conversion) or Recent Customers (broader awareness). Restock emails consistently produce 2-3x the CTR of standard product emails because they address a known demand signal.

Type 3: Deal and coupon campaign

Coupon offer, Lightning Deal alignment, or category-wide promotion announcement. Best segment: Cart Abandoners during the deal window (highest CTR). Deal campaigns trigger urgency — "20% off, today only" headlines outperform "save on our products" framing by 4-5x.

Type 4: Brand story content

Founder story, sourcing narrative, customer-impact piece, or behind-the-scenes content. Best segment: Repeat Customers (loyalty audience). Brand story campaigns do not drive immediate CTR but build long-term affinity that compounds across all future campaigns. Run 1-2 per quarter.

Type 5: Seasonal / event

Holiday-aligned, Prime Day, Black Friday, category-specific event campaigns. Best segment: All Followers (broadest reach for seasonal moments). Seasonal campaigns benefit from advance planning — 2-3 week lead time before the event with reminder sends layered in.

Type 6: Loyalty appreciation

"Thank you" emails to high-value customers, exclusive previews, early access to new products. Best segment: High-Spend Customers (small but engaged). Loyalty emails produce the highest brand affinity per send and have outsized retention impact relative to their cost.

The quarterly mix recommendation

A typical 90-day MYCE program ships approximately 18-24 campaigns across 6 content types. The recommended mix: 40% new product launches and restocks, 25% deal/coupon, 15% brand story, 10% seasonal, 10% loyalty. Adjust based on your product launch calendar and deal frequency.

Subject line + creative best practices

Subject lines and hero images are the two creative variables that drive open rate and CTR. Everything inside the email is downstream of those two decisions.

Subject line patterns that work

• Curiosity hooks — "The product you've been asking for" / "Something new is here"
• Specificity — "200 units only" / "Tuesday 9AM ET" / "First to 500 customers"
• Personalization signals — "Based on your last order" / "For our recent customers" (when targeting Recent Customers segment)
• Direct value — "$20 off your favorites today" / "Free shipping through Sunday"

Subject line patterns to avoid

• All-caps lock — AMAZON FILTERS this and reduces deliverability
• Excessive punctuation — "!!! NEW PRODUCT !!!" lowers placement and reads spammy
• Generic "newsletter" language — "Brand Update" or "Monthly News" underperforms specific framing
• Misleading subject lines — if the email is not actually about a sale, do not include "sale" in the subject

Hero image specifications

• Aspect ratio: 16:9 horizontal works across all template variants
• Resolution: 1500x844 minimum, 3000x1688 ideal for retina/high-DPI displays
• Text overlay: minimal — the email headline carries the copy, the image carries product visualization
• Brand consistency: match the lifestyle/studio aesthetic used in your main Amazon photography — recipients should recognize your brand visually

The 7-second test

If a recipient cannot understand what you are emailing about within 7 seconds of opening, the email fails. Subject line + hero image + headline + single CTA. Anything beyond that hierarchy gets ignored. Brands that send multi-section, multi-product, multi-CTA emails consistently underperform brands sending single-focus emails.

The weekly send cadence calendar

1-2 sends per week is the sustainable cadence for most brands. Below is a typical 4-week cadence calendar showing send slots across segments. The structure prevents list fatigue while maintaining enough touch points to build familiarity.

Why Tuesday + Friday

Tuesday morning sends consistently outperform other weekdays in Amazon-channel email. Recipients have processed Monday's inbox volume and are in active shopping mode by Tuesday. Friday sends catch end-of-week purchasing decisions and weekend deal browsers. Mondays underperform (inbox saturation); Saturdays and Sundays underperform for transactional intent (consumer leisure browsing without buy mode).

The 8-campaign per month math

At 2 sends per week for 4 weeks = 8 campaigns per month or 24 campaigns per 90-day quarter. With the recommended mix across content types, this produces meaningful per-segment exposure without overwhelming any single audience. Each segment receives between 1-3 emails per month, varying by campaign relevance.

When to deviate from 2 per week

Major launch weeks, Prime Day, Black Friday/Cyber Monday, and category-specific peak events justify 3-4 sends per week temporarily. The list tolerates short-term high cadence around clear high-value moments. The cadence should return to 1-2 per week immediately after the event. Brands that try to sustain 3+ sends per week year-round consistently see degraded open rates by month 3.

Open rate and CTR benchmarks

The performance math of MYCE tells you whether your program is on track. Industry benchmarks bound the range; segment + content type combinations determine where in the range you should land.

Why deal campaigns crush CTR

Deal and coupon campaigns reliably hit the high end of every benchmark because they address a specific, time-bound buying decision. The Cart Abandoners segment is also pre-qualified by intent — they already added the product to cart. The combination of high-intent audience plus high-urgency offer produces 3-5x normal CTR.

Why brand story has low CTR but matters

Brand story campaigns produce the lowest direct CTR (1-2%) because there is no immediate purchase trigger. The value is downstream: brand affinity, retention lift, and higher response rates on subsequent product launches. Brands that drop brand story sends "because the CTR is bad" miss the compounding effect — future product launches to that audience perform 15-25% better with brand-story-primed recipients.

The attributed revenue tracking

MYCE attributes orders within 14 days of email open. Standard attribution: a recipient opens a campaign on Tuesday, buys on Friday — attributed to the campaign. The 14-day window captures most influenced purchases. Brands measuring attributed revenue typically see $10-$40 attributed revenue per email sent across a well-mixed program.

MYCE vs Klaviyo: when each

MYCE and Klaviyo are not competitors. They are complementary channels addressing different customer touchpoints. Brands running both consistently outperform brands running either alone.

What MYCE does best

• Amazon channel customer engagement — reaches customers who shopped your brand on Amazon
• Zero-cost infrastructure — no per-email charge, no list management, no deliverability work
• Brand-follower audience — the only way to email people who follow you on Amazon but never purchased
• Amazon-attributed revenue — clicks route back to Amazon listings with first-party attribution

What Klaviyo does best

• Owned customer data — you own the email list and can use it across channels (SMS, ads, retargeting)
• Creative flexibility — full control over template, design, automation logic, segmentation
• Behavioral automation — abandoned cart sequences, post-purchase flows, win-back series, all triggered automatically
• Cross-channel orchestration — coordinate email with SMS, push, paid retargeting, organic social

The integrated program structure

The brands that run both channels effectively use MYCE for Amazon-channel campaigns and Klaviyo for owned-channel email infrastructure. Same creative themes, adapted to each channel. Same product launches, sent to both audiences. The recipient overlap is minimal — most customers are reachable through one channel or the other, rarely both.

The "cannot replace" reality

MYCE cannot replace Klaviyo because Amazon retains the email addresses. If a brand wants to email customers about non-Amazon initiatives (DTC site launches, retail partnerships, brand evolution), Klaviyo is the only option. Brands that try to make MYCE the sole email channel limit their long-term customer relationship infrastructure to what Amazon allows.

Integration with Posts, Brand Story, A+

MYCE is part of Amazon's brand-to-customer relationship stack. Optimizing MYCE in isolation misses the compounding value. The three other brand touchpoints feed and are fed by MYCE.

Amazon Posts → MYCE

Amazon Posts drives brand follower acquisition. Every shopper who follows your brand from a Post becomes addressable through MYCE. Brands posting daily build their MYCE audience 2-4x faster than brands posting weekly. The follower-acquisition flywheel is: Posts engagement → followers → MYCE audience → campaign sends → orders → recent customer audience grows.

Brand Story → MYCE

The Brand Story module on your listings tells the brand narrative to first-time shoppers. The MYCE Brand Story content type extends that narrative to repeat customers via email. Same story arc, two surfaces. Brands with a strong Brand Story module typically run more effective brand-story MYCE campaigns because the audience already has narrative context.

A+ Content → MYCE

A+ Content drives the conversion rate of shoppers arriving at your listings via MYCE clicks. A weak A+ Content layout means MYCE campaigns generate clicks that fail to convert. A strong A+ Content layout amplifies MYCE CTR by 30-50% because more clicks turn into orders. The MYCE-A+ pairing is critical: optimize both as one system.

The combined stack ROI

Brands running all four touchpoints (Posts + MYCE + Brand Story + A+ Content) typically see 25-40% lift on Amazon-channel revenue from existing audiences within 6-9 months. The compounding is not additive — each touchpoint amplifies the others. Posts feed MYCE audience. MYCE feeds Brand Story familiarity. Brand Story feeds A+ conversion. A+ converts MYCE clicks. The flywheel produces outsized returns vs running any single touchpoint at maximum.

Measuring MYCE ROI

Because MYCE costs nothing to send, ROI calculations are dominated by the operational and creative cost. The math is unusually favorable.

The cost stack

• Per-email cost: $0 (Amazon does not charge)
• Creative production: $100-$400 per campaign (hero image refresh, headline copy, body copy)
• Operational time: 30-60 minutes per campaign for segment selection, scheduling, send
• Quarterly review: 2-4 hours per quarter for performance analysis and calendar refinement

The revenue stack

• Attributed revenue per email: $10-$40 (varies by content type and segment match)
• Indirect lift on branded search: 5-15% lift in branded search volume after consistent MYCE sending
• Repeat purchase rate lift: 8-15% lift in 12-month repeat purchase rate for MYCE recipients vs non-recipients
• Customer lifetime value lift: 15-25% LTV lift for engaged MYCE audience over 24 months

The 90-day ROI calculation

A typical 90-day MYCE program: 24 campaigns at $250 average creative cost = $6,000 total cost. At $10-$40 attributed revenue per email and 8,000 average recipients per campaign = $80,000-$320,000 attributed revenue over 90 days. 13-53x first-quarter ROI. Annualized: 20-100x first-year ROI. The math works because the per-email cost is zero.

The compounding factor

Year 2 MYCE audiences are larger than year 1 (followers and recent customers compound). Year 2 creative templates are refined from year 1 learning. Year 2 ROI typically exceeds year 1 by 30-50% with the same operational input. The channel rewards programs that stay consistent over multiple quarters.

How Evolve Media runs client MYCE programs

MYCE program management is one of EMA's recurring deliverables for Brand Registry clients. Most brands have the audience but lack the operational discipline to send weekly.

The 90-day MYCE sprint

Customer segment audit, 90-day campaign calendar aligned to product launches and deal calendar, creative production for 24 campaigns (hero images, headlines, body copy), weekly send execution, performance tracking, monthly review with calendar refinement.

The campaign brief workflow

Every campaign starts with a 2-line brief: (1) what is this campaign about, (2) which segment receives it. From the brief, EMA produces the hero image, subject line, headline, body copy, and CTA. Brand reviews and approves before send. The disciplined brief-to-send workflow produces 8 campaigns per month sustainably.

Integration with broader Amazon strategy

MYCE work integrates with Amazon Posts content production (same creative themes, two surfaces), Brand Story module refreshes (narrative consistency across touchpoints), and Amazon's Choice badge strategy (MYCE-driven sales velocity feeds badge signals).

Performance reporting cadence

Monthly performance review: open rate by campaign type, CTR by segment, attributed revenue, audience growth across all 5 segments, calendar performance vs plan. Quarterly strategic review: top-performing creative patterns, underperforming campaign types to drop, audience growth trajectory, next-quarter content mix refinement.
