Inbox placement tests across major ISPs (Gmail, Outlook, Yahoo), using seeded accounts and spam-trap checks.
Authentication checks (DKIM / SPF / DMARC) and the ease of setting them up.
Automation build tests: welcome series, abandoned-cart flows, transactional triggers, and cross-channel sequences (email + SMS/WhatsApp).

Platform deep dives

Brevo — Best budget and multichannel entry point

One-line summary: Low-cost, multichannel platform that makes basic automations and transactional emails simple to run.

Best for: Small teams that need email plus SMS/WhatsApp without juggling multiple vendors.

Free tier: 300 emails/day (~9,000/month) to unlimited contacts. Paid from: ~ $9/month (scales with volume and features).

Pros: Affordable entry, SMS/WhatsApp support, many integrations (~150+).

Cons: Free send limits restrict high-cadence newsletters; advanced segmentation and enterprise features are limited.

Brevo is a practical starting point for teams that need basic automation and multichannel messaging without high costs.

Tip: Use Brevo’s free tier to centralize contacts, then test deliverability with a seeded list before moving large campaigns.

Omnisend — Best for e‑commerce automation and revenue tracking

One-line summary: Built to recover carts and attribute revenue to email/SMS flows.

Best for: Shopify and WooCommerce stores that need advanced abandoned-cart and lifecycle automation.

Free tier: 250 contacts and 500 monthly sends. Paid from: ~ $16/month (500 contacts).

Pros: Robust commerce workflows, revenue attribution, many e‑commerce integrations.

Cons: Free tier too small for most growing stores; costs rise with contact count and sends.

Omnisend is purpose-built for commerce: it’s the best pick when cart recovery and revenue tracking are priorities.

Tip: Link Omnisend to your store early and test attribution windows so revenue shows up in the right campaigns.

Kit (formerly ConvertKit) — Creator-first, monetization-ready

One-line summary: Creator-focused platform with a generous free subscriber allowance and built-in paid subscriptions via Stripe.

Best for: Writers, podcasters, and course creators who want to monetize directly.

Free tier: Up to 10,000 subscribers (may require displaying partner recommendations). Paid from: ~ $29/month.

Pros: Large free tier, simple paid-sub flows, native Stripe integration.

Cons: Fewer advanced automation features than commerce stacks; partner recommendation requirement on the free tier.

Kit gives creators a fast path to paid subscriptions without complex tech setups.

Tip: Use the free tier to validate a paid newsletter before moving to a paid plan; ensure Stripe is set up and tested.

Beehiiv — Growth mechanics and publisher monetization

One-line summary: Publisher-focused platform built around referrals, analytics, and an ad network.

Best for: Publishers and newsletters that want to scale via viral loops and ad revenue.

Free tier: Up to 2,500 subscribers. Paid from: ~ $49/month.

Cons: Integration count smaller than some competitors; costs climb with scale.

Beehiiv is designed for audience growth and monetization beyond subscriptions.

Substack — Simplest path to paid subscriptions and discovery

One-line summary: Minimal setup for publishing and paid subscriptions, with a built-in discovery audience.

Best for: Writers who want minimal technical overhead and platform discovery.

Free tier: Free to publish; paid subscriptions processed via Stripe. Platform fee: 10% revenue share on paid subscriptions.

Pros: Extremely easy to start, built-in audience network, payments handled for you.

Cons: No advanced automation, limited segmentation and A/B testing, platform fee reduces net revenue.

Substack trades advanced features for the fastest route to paid subscriptions and in‑network discovery.

Tip: Use Substack for MVP monetization or when platform discovery outweighs owning the stack.

Important trade-offs and decision checklist

Free-tier fit: Match free limits to your expected monthly sends (subscribers × sends per month).
Pricing model: Per-subscriber pricing scales with list size; per-send or flat plans can be cheaper for high cadence.
Deliverability: Inbox placement beats open rates for long-term ROI—check authentication and seed-list results.
Monetization: Revenue share (Substack), built-in Stripe (Kit), or ad networks (Beehiiv) affect net income and control.
Integrations: E‑commerce teams should verify native Shopify/WooCommerce connectors and revenue reporting.
Migration friction: Export, tags, paid-subscriptions handling, and DNS changes matter more than you think.

Pricing scenarios (illustrative guidance — approximate, Jan 2026)

Use these to see which free tier or starter plan might work based on send volume. These are rough, conservative checks using published free limits and starter prices; exact paid pricing will vary by usage.

Scenario A — Creator: 5,000 subscribers, 2 emails/week (≈8 sends/month)

Total monthly sends: 5,000 × 8 = 40,000 sends.
Kit: Free tier supports up to 10,000 subscribers — platform fees may be zero for this volume; Stripe payment processing still applies.
Brevo: Free tier limit ~9,000 sends/month — insufficient for 40,000 sends; a paid Brevo plan will be required.
Beehiiv: Free tier caps at 2,500 subscribers — insufficient; paid plan required.
Conclusion: Kit can be free; Brevo and Beehiiv would need paid tiers for this cadence.

Scenario B — Publisher: 50,000 subscribers, daily sends (≈30 sends/month)

Total monthly sends: 50,000 × 30 = 1.5 million sends.
Free tiers are universally insufficient. Expect enterprise or high‑tier plans and deliverability services.
Key decision: choose a vendor with proven ISP relationships and a clear plan for IP warm-up and dedicated sending.

Scenario C — E‑commerce: 20,000 subscribers + transactional volume

Mix of marketing and transactional sends makes vendor choice important—transactional SMTP support and API reliability matter.
Omnisend’s commerce workflows and attribution are purpose-built for this; Brevo supports transactional emails too.
Evaluate how each vendor separates transactional vs marketing sends (affects deliverability and cost).

How to test deliverability before you commit

Run a short deliverability audit using these steps:

Set up SPF, DKIM, and DMARC records on your sending domain.
Create a seed list of test accounts across Gmail, Outlook, Yahoo, Apple Mail, and niche providers.
Send identical campaigns across candidate platforms and measure inbox placement over 2–4 weeks.
Check spam impressions, bounces, and spam-trap hits; review sender reputation and IP history.
Benchmark: aim for inbox placement >85% as a healthy target; 70–85% needs remediation; <70% is a red flag.

Migration checklist — what to plan for

Export subscribers with tags and segmentation metadata (CSV/JSON).
Map paid subscribers and reconcile payment IDs (Stripe/processor exports).
Pause automations on the old platform and recreate critical flows (welcome, transactional) first.
Update DNS (SPF/DKIM/DMARC) and allow time for propagation and IP warm-up.
Run a staged migration: 1,000–5,000 test sends, then ramp while monitoring inbox placement.
Retire old templates only after ensuring links, images, and tracking work on the new platform.

How AI fits into newsletter software (practical uses and risks)

AI is a powerful productivity lever when paired with a capable platform. Practical use cases:

Subject-line and preview text generation with multivariate testing.
Automated segmentation based on engagement patterns and predicted churn risk.
Personalized content blocks—dynamic sections that swap copy or offers per recipient.
Summaries and repurposing: turn a long post into multiple short newsletter variants.

Integration tips:

Use platform-native AI features where available to avoid fragile one-off integrations.
For custom workflows, call LLM APIs (e.g., ChatGPT) server-side and validate outputs before sending.

Risks and guardrails:

Hallucinations: always human-review AI-generated claims or facts.
Data privacy: ensure PII isn’t leaked to third-party models without proper safeguards.
Over-personalization: too much tailoring can feel creepy—favor useful relevance over invasive detail.

Benchmark KPIs and when to re-evaluate your platform

Deliverability (inbox %): Target >85%. If it drops below 80% consistently, act.
Open rate: Varies by niche—track trends rather than absolute numbers.
Click-through rate (CTR): Monitor for engagement quality; declines often indicate list fatigue.
Conversion / revenue per send: Especially crucial for e‑commerce teams—use attribution windows.
Cost per 1,000 engaged users: Recalculate annually as list size and cadence change.
