Loops vs Omnisend in 2026: SaaS product email vs eCommerce email and SMS
Loops sends the email that keeps a SaaS product's users engaged: onboarding, transactional, lifecycle. Omnisend sends the email and SMS that keeps an online store's customers buying: abandoned cart, browse abandonment, post-purchase. Both are simple to start; they solve different businesses' problems.
Loops
Omnisend- Omnisend includes native SMS and push notifications on every plan including Free; Loops has no SMS or push notification capability at all.
- Loops covers transactional email (password resets, receipts) alongside marketing email in one account; Omnisend's own feature list is centered on marketing and lifecycle, not developer-triggered transactional sends.
- Omnisend offers free migration service from Klaviyo, Mailchimp, and other platforms; Loops has no equivalent migration offer in its own data.
- Loops charges by subscribed contact count with no per-seat fee; Omnisend's Free plan caps sends at 500/month and its paid tiers scale with list size as well as unlocking A/B testing.
- Both platforms have added MCP integration, letting AI tools connect directly for workflow automation.
- Omnisend's pre-built automation templates cover eCommerce-specific scenarios like browse abandonment and win-back; Loops' automations trigger on generic SaaS events like signup, trial start, and feature activation.
- Loops has official SDKs for Node, Next.js, Ruby, PHP, and NuxtJS aimed at developers; Omnisend's workflow builder is designed for non-technical marketers with drag-and-drop templates.
Loops and Omnisend both offer a free tier and pride themselves on simplicity, but the resemblance stops at ease of use. Loops is built for SaaS companies that need marketing, product lifecycle, and transactional email in one account with a clean developer API, trusted by Framer, Linear, and Perplexity. Omnisend is built for eCommerce brands running email and SMS together, with pre-built workflows for abandoned cart and post-purchase flows, used by over 150,000 online stores. A subscription box brand and a B2B SaaS startup are not choosing between these two tools for the same reason, even though both could technically send a welcome email.
The tools at a glance
Loops
Unified email platform for SaaS teams covering marketing, product, and transactional email from a single simple interface
Loops organizes everything around four ideas: contacts, contact properties, events, and event properties. That model maps directly onto how a SaaS product actually generates email triggers, signup, trial start, payment, feature activation, and the same simplicity extends to the API, which ships with SDKs for Node, Next.js, Ruby, PHP, and NuxtJS.
Marketing campaigns, lifecycle sequences, and transactional sends like password resets all run from the same account and domain, which removes the need for a separate transactional email vendor. Pricing is based on subscribed contact count with no per-seat charge, and the free plan covers up to 1,000 subscribers and 4,000 sends a month to validate the integration.
What Loops does not have is any SMS or push notification channel, or eCommerce-specific automation like abandoned cart recovery tied to product purchase events. It also is not designed for cold outreach. Its scope stays deliberately narrow: email for a SaaS product's users, not multi-channel retail marketing.
| Feature | Free $0/mo | Paid (contact-based) Starts at ~$49/mo |

| Transactional email | Limited | ✓ |
| SMS / push notifications | ✗ | ✗ |
| Team seats | Unlimited | Unlimited |
| MCP server | ✓ | ✓ |
Omnisend
Email and SMS automation for eCommerce with a free tier, flat-rate pricing, and free migration from other platforms
Omnisend is scoped narrowly to eCommerce, and its automation templates reflect that directly: welcome series, abandoned cart recovery, browse abandonment, post-purchase follow-up, and win-back campaigns come pre-built rather than requiring a custom workflow from scratch. Over 150,000 online stores use the platform.
Email and SMS run from the same workflow builder, so a cart abandonment sequence can start with an email and escalate to SMS if it goes unopened, with push notifications available as a third channel. The free plan covers 500 emails a month, and Omnisend's free migration service handles the technical transfer for stores switching from Klaviyo, Mailchimp, or another platform.
The tradeoff is scope: Omnisend has no transactional email feature comparable to Loops, no developer SDKs for building custom event triggers into a product, and SMS is billed separately per message starting at $0.007. For a B2B SaaS product with no purchase events to automate around, most of Omnisend's pre-built workflows simply do not apply.
| Feature | Free $0/mo | Standard From $11.20/mo | Pro From $41.30/mo | Custom Contact |
|---|---|---|---|---|
| SMS Campaigns | ✓ | ✓ | ✓ | ✓ |
| Push Notifications | ✓ | ✓ | ✓ | ✓ |
| A/B Testing | ✗ | ✓ | ✓ | ✓ |
| Free Migration | ✗ | ✓ | ✓ | ✓ |

Which should you choose?
LoopsOmnisendLoopsOmnisendOmnisendLoopsThese two rarely show up on the same shortlist because they serve different businesses at a structural level. Loops exists because SaaS products generate behavioral events, signup, trial, payment, that need to trigger email without a developer building a separate transactional pipeline. Omnisend exists because online stores generate purchase and browsing events that need pre-built, non-technical automation across email and SMS. Neither company built the other's core workflows, and neither should.
Bottom line
Pick Loops if you run a SaaS product and need onboarding, lifecycle, and transactional email from one simple, developer-accessible platform with no per-seat cost. Pick Omnisend if you run an online store and need abandoned cart recovery, SMS, and post-purchase automation without building it from scratch, especially if you are migrating away from a more expensive platform like Klaviyo. If your business genuinely straddles both, a SaaS product with an attached eCommerce storefront, expect to run both tools rather than force one to cover the other's job.
Frequently asked questions
Can Loops handle SMS marketing the way Omnisend does?
No, Loops has no SMS or push notification capability at all; it is an email-only platform for marketing, lifecycle, and transactional sends. Omnisend includes SMS and push notifications on every plan including its free tier, billed separately per SMS message starting at $0.007.
Is Omnisend a good fit for a B2B SaaS company instead of Loops?
Not really. Omnisend's automation templates, abandoned cart, browse abandonment, post-purchase, are built around eCommerce purchase events that a typical B2B SaaS product does not generate. Loops is purpose-built for SaaS behavioral events like signup and trial activation, which makes it the better-matched tool for that use case.
Does Loops offer free migration from another platform like Omnisend does?
No, Loops' own published data does not describe a free migration service. Omnisend offers free migration, including handling the technical transfer of contacts, segments, templates, and workflows, for stores moving from Klaviyo, Mailchimp, or similar platforms, available from its Standard plan up.
Which platform has better transactional email support, Loops or Omnisend?
Loops is the stronger choice for transactional email; it is built to handle password resets, receipts, and account notifications in the same account as marketing and lifecycle email via a single API call. Omnisend's feature set centers on marketing and lifecycle automation rather than developer-triggered transactional sends.
How does pricing compare between Loops and Omnisend at a similar list size?
Both price by contact count. Loops' paid tier starts around $49/month with no per-seat fee, and its free plan covers up to 1,000 subscribers. Omnisend's Standard plan starts from $11.20/month and scales with list size, with its free tier capping at 500 sends per month, though Omnisend's SMS costs are billed separately on top of the plan price.
Does Loops support the Model Context Protocol like Omnisend does?
Yes, both platforms have added MCP server integration, letting AI tools and agents connect directly to trigger emails, manage contacts, or automate workflow tasks without manual interaction with either platform's interface.
