The short answer

The wrong platform rarely hurts on day one. It hurts after the list, revenue, and automations grow. Decide whether the newsletter is the product, sells the product, or supports a customer journey—then price the entire system at the point you expect to reach.

01

Start with what the email must accomplish

A publisher needs an archive, discovery, paid subscriptions, and sponsorship tools. A creator selling courses needs tagging, sequences, and commerce. A service business needs lead stages and behavior-triggered follow-up. Those are different operating systems. Choose the job first; otherwise a polished editor can hide a structural mismatch.

02

Price the behavior, not the headline plan

Forecast active contacts, stored contacts, monthly sends, audiences, seats, automations, and paid revenue at 1,000, 10,000, and 50,000 readers. A subscriber-priced service punishes list growth; a send-priced service punishes frequency; a revenue-share service becomes expensive only after paid conversion. The cheapest starting plan and the cheapest successful plan are often different products.

03

Make deliverability a launch requirement

Use a domain you control and verify SPF, DKIM, and DMARC before promoting the list. Google requires SPF or DKIM for all Gmail senders; senders above 5,000 daily Gmail messages must use SPF, DKIM, DMARC alignment, and one-click unsubscribe for promotional mail. Keep complaints below Google’s 0.3% threshold. A platform can supply infrastructure, but your consent, targeting, cadence, and list hygiene create the reputation.

04

Treat portability as more than a CSV

Before committing, create test subscribers with source, consent date, tags, custom fields, subscription status, and an unsubscribe. Export everything. Verify that suppression records, paid status, content archives, forms, domains, and automation logic can be preserved or reconstructed. An email address export is useful; a reproducible business is better.
