How to Choose an Email Marketing Platform for Your Startup

Compare Mailchimp, ConvertKit, Loops, and other email platforms to find the right fit for your startup. Evaluate deliverability, automation depth, pricing models, and how well each tool scales with your list.

Key Decision Criteria

List Size and Pricing Model

High Priority

Email platform costs vary dramatically by list size. Some charge per subscriber (Mailchimp, ConvertKit), others per email sent (Loops, Resend). If you have a large list you email infrequently, per-send pricing saves money.

Automation Complexity

High Priority

Simple welcome sequences need basic automations. Product-led growth with behavioral triggers, branching logic, and event-based emails requires platforms like ConvertKit or Loops that handle complex flows without breaking.

Deliverability Reputation

High Priority

The best email never written beats the best email in spam. Shared IP pools on free tiers hurt deliverability. ConvertKit and Loops maintain strong sender reputations. Mailchimp's free tier shares IPs with low-quality senders.

Design vs. Plain Text Focus

Medium Priority

Newsletter brands need rich templates with drag-and-drop editors. Developer tools and B2B SaaS often perform better with plain-text-style emails. Match your tool to your email style to avoid fighting the editor.

Questions to Ask Yourself

Are you sending newsletters, transactional emails, or both?

Newsletters only: Mailchimp or ConvertKit excel here. Transactional only: Resend is purpose-built for developer-triggered emails. Both: Loops handles marketing and transactional in one platform, avoiding the need for two tools.

How large is your email list, and how fast is it growing?

Under 1,000 subscribers: Most free tiers cover you. 1k-10k: Compare per-subscriber pricing carefully — Mailchimp gets expensive here. 10k+: Negotiate annual plans or switch to per-send pricing with Loops.

Do you need event-based triggers from your product?

If you want to send emails based on user behavior (signed up, completed onboarding, went inactive), you need a platform with API-driven event triggers. Loops and Resend handle this natively. Mailchimp requires Zapier or custom integrations.

How much time can you spend on email design and setup?

Minimal time: Loops has a clean, minimal editor built for fast iteration. More time available: Mailchimp's template library and drag-and-drop builder give more design control but take longer to set up.

Red Flags to Watch For

Platform charges for unsubscribed contacts on your list

Some platforms count unsubscribed or inactive contacts toward your billing limit. Mailchimp historically charged for unsubscribed contacts. Verify you only pay for active, reachable subscribers.

No built-in analytics beyond open rates

Open rates are increasingly unreliable due to Apple Mail Privacy Protection. Your platform should track click rates, conversion events, and revenue attribution. Without these, you're flying blind on what actually works.

Requires third-party tool for basic automations

If sending a welcome sequence or re-engagement flow requires Zapier or a developer, the platform is too limited for marketing. Basic automation should be built in and visual.
