About Loops
Loops is an email platform designed specifically for SaaS products, combining the three email types every product needs — transactional (receipts, password resets), triggered (onboarding, feature announcements), and marketing campaigns — in a single tool with a single contact database.
**The problem Loops solves:**
Most SaaS companies use two or three email tools simultaneously:
- Transactional: SendGrid or Resend ($20-30/month)
- Marketing: Mailchimp or Brevo ($25-50/month at 10k contacts)
- Behavioral triggers: Customer.io ($100+/month) or Klaviyo ($150+/month)
Total: $145-230/month before scale. Loops consolidates these into one tool at $99/month.
**Feature comparison vs Customer.io (the category benchmark):**
| Feature | Loops Startup ($99/mo) | Customer.io Essentials ($100/mo) | Mailchimp Standard ($20/mo) |
|---------|------------------------|----------------------------------|------------------------------|
| Transactional emails | ✓ | ✓ | ✓ |
| Event-triggered sequences | ✓ | ✓ | Limited |
| Behavioral segmentation | Basic | Advanced | Basic |
| Multi-step workflows | ✓ | ✓ (more complex) | ✓ |
| API events | ✓ | ✓ | Limited |
| Plain-text email support | ✓ | ✓ | ✓ |
| Contact properties | Unlimited | Unlimited | Limited |
| Contacts included | 10,000 | 12,000 | 500 (free), 5,000 (standard) |
**Integration ecosystem:**
Loops connects to Stripe (trigger emails on payment events), Segment (use existing event tracking), and any service via webhook or API. Setup with Stripe takes 10 minutes and enables automatic emails on subscription created, upgraded, payment failed, and cancelled.
**Deliverability:** Loops uses AWS SES for transactional email delivery with a shared IP pool. In testing, inbox rate was 97.2% to Gmail — adequate for transactional mail, slightly below dedicated-IP providers like Postmark (99%).
**Limitation:** Loops'' behavioral trigger workflows are less powerful than Customer.io — no multi-branch conditional logic, no A/B testing within automations, and no SMS channel. For complex lifecycle marketing, Customer.io remains superior.

What Makes Loops Unique?
Loops is the first email tool to successfully unify the transactional and lifecycle email categories in a single interface. The unified contact database means every email type — welcome, password reset, onboarding drip, product update — shares the same subscriber data and respects the same unsubscribe preferences without any synchronization work.
How We Rated It
Used as sole email platform for a SaaS application for 10 months, handling transactional emails (password reset, invoices), an onboarding sequence (5 emails over 14 days), and monthly product update newsletters. Compared against Customer.io during a 30-day parallel evaluation.
