How Skims Uses Klaviyo & Drop Culture to Power a $5B Email Machine
Skims sends approximately 5 emails per week using Klaviyo as their ESP and Attentive for SMS, with lifecycle automations covering welcome, abandoned cart, restock alerts, and promotional drops. We tore apart their signup flow, DNS authentication, and subject line patterns.
Why Email Is Skims' Secret Weapon
The ROI data behind why a $5B DTC brand invests heavily in email and SMS
Email is the highest-ROI marketing channel in existence — and Skims treats it like a product launch engine, not a broadcast tool. While Kim Kardashian's massive social following generates the headlines, email and SMS quietly drive the conversion engine behind a brand valued at $5 billion (verified fact, November 2025, per CNBC). Here's why:
Email marketing returns $42 for every $1 spent — higher than paid social ($2-5), paid search ($8-10), and organic social ($0). No other channel comes close. For DTC fashion and intimates brands like Skims, the ROI can be even higher due to repeat purchase behavior.
DTC brands attribute 15-25% of total ecommerce revenue to email. For a brand approaching $1 billion in annual sales like Skims, that means email could be driving $150-250 million in revenue annually. Combined with their paid media strategy, email forms the backbone of their retention engine.
Skims' revenue grew approximately 7x in five years — from ~$145M in 2020 to an expected $1B+ in 2025. This growth trajectory requires aggressive retention marketing, and email is the only channel that scales predictably at this pace without proportional spend increases.
You don't need Kim Kardashian to copy Skims' email playbook. The strategic patterns — drop-culture subject lines, aggressive cart recovery, Attentive SMS integration — work at any scale. What makes Skims interesting is how they've built a retention machine that converts celebrity-driven awareness into repeat purchases through systematic lifecycle automation.

Signup Flow Analysis
We signed up and documented every step — popup triggers, form fields, and conversion tactics
Skims' email capture combines a generous discount with dual-channel opt-in for email and SMS. Unlike brands that separate these entirely, Skims bundles the signup experience. Every data point here is verifiable by visiting skims.com or their dedicated join-the-list page.

Evergreen Offer
Skims trades signup conversion rate for subscriber quality. By requiring both email and phone number upfront, they capture fewer subscribers but each one enters both the Klaviyo email flow and the Attentive SMS flow simultaneously. This is the opposite of the Gymshark approach (email-only, minimal friction) and reflects Skims' bet that their brand strength — driven by Kim Kardashian's celebrity pull — is strong enough to overcome the extra friction. For most brands under $50M ARR, we'd recommend the Gymshark pattern instead.

ESP & Email Infrastructure
DNS records, sending domains, and authentication — all publicly verifiable
DNS records don't lie. Skims runs a multi-provider email infrastructure with Klaviyo as the primary ESP, SendGrid for transactional delivery, and Proofpoint for inbound email security. For a full breakdown of their tech stack, see our tech stack analysis.
ESP Detection
Skims uses Klaviyo as their primary email service provider (ESP), confirmed via third-party technology detection (Panoramata, BuiltWith). This is consistent with their Shopify Plus e-commerce platform, which integrates natively with Klaviyo. Transactional emails route through SendGrid, confirmed via DKIM records pointing to sendgrid.net.

DMARC Record
$ nslookup -type=TXT _dmarc.skims.com _dmarc.skims.com. 300 IN TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc_agg@vali.email; aspf=r; adkim=r;" ; DMARC policy: quarantine — suspicious emails are flagged, not rejected ; Valimail handles DMARC aggregate reporting ; Relaxed SPF and DKIM alignment (aspf=r, adkim=r)
Authentication Grade
Skims' email authentication is solid but has room for improvement. The multi-provider SPF record (Shopify, SendGrid, Amazon SES, Mailgun) suggests a complex email infrastructure with multiple sending paths. The DMARC quarantine policy is good but not best-in-class — upgrading to reject would provide stronger protection against spoofing. The inclusion of KnowBe4 in SPF indicates they run phishing simulation training for employees. See how this integrates with their tracking and analytics setup.

What We Know About Their Lifecycle Flows
Based on email archive analysis, third-party teardowns, and direct observation
Skims runs a drop-culture-driven email program with aggressive lifecycle automation. Their email strategy centers on creating urgency through limited drops, restock alerts, and time-sensitive promotions. We can reconstruct much of their flow architecture from email archives and third-party analyses.
Welcome Series
Skims' welcome email takes a notably different approach from most DTC brands — it focuses on brand voice and value proposition rather than repeating the discount code (which was already delivered at signup):
Skims' welcome email intentionally omits the discount code. This is a deliberate brand decision — the welcome email focuses on brand storytelling and category introduction, not promotion. The discount was already delivered during signup confirmation. This approach prioritizes brand perception over immediate conversion, which makes sense for a brand positioned in the premium intimates space.

SMS Strategy (Attentive)
Skims uses Attentive for SMS/MMS marketing, confirmed via their SMS terms page hosted at attn.tv/skims/terms.html. Their short code is 68805 (text "SKIMS" to opt in). Every SMS includes an image (MMS format), making the text thread visually rich with product imagery. SMS covers new drops, restocks, promotional events, and cart reminders. Their pricing and discount strategy is closely coordinated across email and SMS channels.
