Shopify Email Marketing Apps Compared: Klaviyo vs Omnisend vs Drip vs Privy
Email marketing is the highest-ROI channel for most Shopify stores — but it's also one of the most over-paid-for. Many merchants end up with two email tools billing simultaneously and don't notice for months.
The Overlap Trap
The most common email billing mistake we see in AppTrim scans: a merchant installs Klaviyo (for advanced flows), then installs Privy (for popups), and doesn't realise Privy also charges a separate email sending fee once they enable campaigns. They're paying Klaviyo and Privy for email, with list overlap of 90%+.
Less commonly: merchants migrating from Drip to Klaviyo but leaving the Drip subscription running. Or using both Omnisend and Klaviyo because "one came with the theme." Before comparing apps, check whether you're already paying for two.
Pricing at a Glance
| App | Free Tier | 1K contacts | 5K contacts | 10K contacts |
|---|---|---|---|---|
| Klaviyo | Up to 250 contacts | $45/mo | $175/mo | $275/mo |
| Omnisend | 250 contacts / 500 emails | $16/mo | $65/mo | $115/mo |
| Drip | None | $39/mo | $89/mo | $154/mo |
| Privy | Popups free (100 contacts) | $30/mo | $45/mo | $70/mo |
Prices as of May 2026. Klaviyo charges per active subscriber profile; others by contact count. Annual billing saves ~20% on most plans.
Klaviyo
Klaviyo is the market leader and for good reason: its Shopify data model is first-class. Every purchase event, abandoned cart, viewed product, and refund syncs in real time and is queryable in segmentation. Flows (automated sequences) can branch on 50+ conditions out of the box. If you run any kind of volume-dependent segmentation — win-back, VIP tiers, post-purchase sequences — Klaviyo is the strongest tool.
The catch: pricing scales steeply with list size. At 10K contacts, you're at $275/mo. At 50K contacts, expect ~$700/mo. And Klaviyo counts all profiles — including churned subscribers and anyone who's unsubscribed. Active list hygiene is mandatory, or you pay for contacts who will never open another email.
Best for
- • Stores with $500K+ annual revenue
- • Complex multi-step flow logic
- • Heavy segmentation (RFM, LTV)
- • Teams who use predictive analytics
Not ideal for
- • Sub-$100K stores on tight margins
- • Stores that rarely send campaigns
- • Teams who want simplicity over power
- • Dirty lists with lots of unengaged profiles
Omnisend
Omnisend is the best-value option for most mid-market Shopify stores. At the same contact count, it typically runs 35–50% cheaper than Klaviyo, and the included SMS credits on paid plans are a genuine differentiator. The automation builder has improved substantially since 2024 — branching, A/B split, and product recommendations are all solid.
Where it falls short: the deep Shopify data model that Klaviyo has (browsing events, predictive LTV, custom catalog properties) is thinner. Segmentation is contact-level, not event-level. If you want to send to "people who viewed Product X and then purchased Product Y but never bought from category Z," Klaviyo is better. For standard abandoned cart, welcome, and win-back flows, Omnisend does the job at a lower price.
Best for
- • Stores wanting email + SMS bundled
- • $100K–$500K revenue range
- • Teams switching from Mailchimp
- • Standard automation flows (not custom)
Not ideal for
- • Event-level behavioral segmentation
- • Predictive analytics users
- • High-SKU catalogs with complex rules
- • Large teams needing role-based access
Drip
Drip pioneered ecommerce CRM before Klaviyo grew into the category leader. Its visual workflow builder is still one of the most intuitive for non-technical marketers, and it has solid WooCommerce parity (useful for merchants migrating from WP to Shopify). But its Shopify data sync is a generation behind Klaviyo, and the product has received relatively little investment in new features over the past few years.
Drip has no free tier, which means new stores pay from day one. At $39/mo for 1K contacts it's slightly cheaper than Klaviyo, but Omnisend undercuts it meaningfully. The main reason to choose Drip today: you're already on it and migrating would cost more in time than the savings are worth.
Migration watch: Many merchants who migrated from Drip to Klaviyo left their Drip subscription running. AppTrim regularly surfaces these ghost Drip charges in invoice scans — $39–$154/mo for a tool with no active lists.
Privy
Privy started as a popup/lead capture tool, not an email marketing platform. The popup builder is still its strongest feature — cart savers, exit intent, spin-to-win wheels, and embedded forms are all strong and easier to configure than Klaviyo's signup forms.
The problem: Privy added email campaigns and automations as a secondary feature, and many merchants don't realize they're paying for email sending on top of their existing Klaviyo subscription. If you installed Privy for popups and enabled any email features to "try them out," you may be billed for email by two tools simultaneously.
The correct use of Privy with Klaviyo: use Privy only for popups and form capture, pipe new contacts into Klaviyo via the native integration, and send all email from Klaviyo. Do not enable Privy email campaigns or automations if you're paying for Klaviyo — you're paying for duplicate capability.
