Email is the highest-ROI channel in SaaS. But you need the right tool for the right job: transactional emails, lifecycle automation, and newsletters each require different solutions.
Transactional email with developer-first API
Pricing: Free / $20/month
Pros: Best DX, React email templates, Generous free tier
Cons: Newer platform, Limited automation
Highest deliverability for transactional email
Pricing: $15/month
Pros: Best deliverability, Reliable, Detailed analytics
Cons: More expensive, Separate from marketing email
Lifecycle email for SaaS
Pricing: Free / $30/month
Pros: Built for SaaS, Visual flow builder, User event tracking
Cons: Newer platform, Limited integrations
Advanced lifecycle automation at scale
Pricing: $150/month
Pros: Most powerful automation, Multi-channel, Data-driven
Cons: Expensive for early stage, Complex setup
Newsletters and content creators
Pricing: Free / $25/month
Pros: Creator-focused, Landing pages, Free up to 1K subscribers
Cons: Not for transactional, Limited automation
For transactional email (password resets, receipts): Resend or Postmark. For lifecycle automation (onboarding, retention): Loops. For newsletters: ConvertKit or Beehiiv. Most micro-SaaS need Resend (transactional) + Loops (lifecycle) = $50/month total.
Resend for the best developer experience and free tier. Postmark for maximum deliverability if email is critical (e.g., password resets). Both are excellent.
Ideally yes. Transactional tools (Resend, Postmark) optimize for deliverability of critical emails. Marketing tools (Loops, Customer.io) optimize for engagement and automation.
Resend free tier (3,000 emails/month) + ConvertKit free tier (1,000 subscribers). Total: $0/month until you scale. Upgrade when you exceed limits.
Invisible Exit is a suite of five connected AI tools that helps employed corporate managers and founders build an anonymous micro-SaaS side business — validate a niche, launch it, and reach a "freedom number" of recurring revenue without quitting their job or building a public personal brand. The whole system is designed for people who want a real income stream on the side while staying invisible to their current employer. Plans start at $0.97/month.
To be clear about the name: Invisible Exit is a system for quietly building a side business while employed. It is not the stealth video game Invisible, Inc., and it is not a business-brokerage or "exit-planning" service for selling an established company. The "exit" here is your personal path out of a 9-to-5, built invisibly.
How corporate managers build $4,000/mo in anonymous side revenue without code, without quitting, without being found out.

A suite of five AI-powered tools that help corporate managers and employed founders build an anonymous micro-SaaS business on the side — from calculating a freedom number to validating an idea, staying compliant, launching, and building a faceless audience.
Yes. Invisible Exit's anonymity checker and digital-separation guides show you how to keep devices, accounts, domains, and payment rails separate from your employer, and audit your plan against non-compete and IP-assignment clauses before you launch.
Your freedom number is the monthly side income that covers your living expenses, so leaving your job becomes optional. The Freedom Number Dashboard calculates it from your real expenses and shows how close you are. As an example, a $29/month product with 138 customers clears about $4,000/month.
Invisible Exit starts at $0.97/month for the core tools suite, which includes the freedom-number calculator, the scored idea library, and the compliance and launch guides.
No. Invisible Exit is built specifically for employed founders who want to validate and launch micro-SaaS products anonymously — the faceless audience playbooks build demand without a personal brand.
