Email marketing free-tier pressure: migration-moment brief and campaign boundary

Email marketing free-tier pressure: migration-moment brief

Summary Small newsletters, creators, local businesses, and agencies testing client lists between 500 and 1,000 subscribers.

This field note is meant for agency operators and founder-led SaaS teams deciding whether a competitor-triggered market change is strong enough to become a migration campaign.

Evidence profile - Readiness: Client-ready brief - Publishability score: 72/100 - Dated or captured change evidence: 1 - Official current-state sources: 0 - Public reaction sources: 1 - Strongest current source: MailerLite (official_dated_change, score 82)

Source boundary One confirmed official dated free-tier reduction, one triangulated Mailchimp reduction, and several current-state constraints. Do not claim a category-wide shrinkage index yet.

Safe use Use MailerLite as the first client-ready migration moment after source review. Treat Mailchimp as triangulated until official dated or archived evidence is captured.

Campaign angle Use the brief when a client competes with a vendor whose pricing, usage cap, feature access, or AI add-on economics now create buyer frustration. The first action should be a narrow migration memo, not a broad category claim.

Recommended next action 1. Open the evidence report and review the source boundary. 2. Create a SwitchSignal workspace for the client category. 3. Add the competitor URLs that matter for the account. 4. Generate a campaign pack only after the before/after, affected segment, and cannot-claim guardrails are clear. 5. Record whether the output became a page, ad group, community response, client memo, sales conversation, pipeline, retained account, or revenue.

Outcome feedback path After running the campaign, record the business outcome in SwitchSignal. The point is not another one-off report; it is learning which competitor-triggered dislocations create repeatable revenue action.
