Five checks before any migration

Run these against both platforms — the source and the destination — before you commit. A migration that fails one of them usually doubles the effort instead of halving it.

What to check	The real question	Why it matters
Billing links	Which automations depend on native billing events (Stripe, Paddle, Lemon Squeezy)?	Rebuilding triggers is the top hidden migration cost
Suppression	Do bounces, complaints, and unsubscribes export cleanly?	Otherwise you repeat deliverability lessons you already paid for
Templates	HTML templates, dynamic content, snippet libraries	Expect a rebuild; budget two weeks of QA, not a weekend
Event history	Product and billing events that drove past sends	Most tools export dashboards, not events
Contracts	Annual commitment, seat minimums, exit clauses	Mid-term migration can cost double; schedule the exit

Pick by job, not by brand

Where the strongest alternatives usually land, depending on the job your sending is built around:

The job	Start with	Why it fits
Stripe / Paddle / Lemon Squeezy SaaS billing events	Sequenzy	Native billing triggers, pay-per-send plans from $19/mo, unlimited contacts (verify current limits)
Catalog-heavy commerce	Klaviyo or Omnisend	Purchase-aware flows from day one; watch profile-based pricing
Deep branching + CRM context	ActiveCampaign or HubSpot	Strong engines priced on contacts + seats
Newsletter-first publishing	MailerLite or Kit	Simplest operations; deep product logic needs plumbing
Budget-tight solo founders	MailerLite or Sequenzy	Usable free tiers; confirm what "unlimited" excludes

Migration FAQ

• What does "native" integration mean here? No custom webhook code required. Anything short of that is an API workaround, and the guides label it as one.
• How risky is switching platforms? Suppression exported, billing links rebuilt, and two weeks of template QA keep risk mostly schedule-side. Rushed migrations re-pay deliverability lessons.
• Should I migrate mid-contract? Usually no; a broken billing integration can flip the math if it is limiting revenue.
• Where do I confirm prices? On each vendor's official pricing pages, linked throughout the guides — figures there are decision lenses with a check-current-plans note, never quotes.
• Do you crown a universal winner? No. What fits a Stripe-first SaaS rarely fits a catalog brand, and the per-platform pages say so.

Pricing snapshot of the tools that usually replace an incumbent

Entry pricing lenses read from official pages on our check dates — never quotes. Confirm on your reading day.

Platform	Entry pricing lens	Free tier	Official source
Sequenzy	$19/mo (20,000 emails/mo)	1,000/mo	sequenzy.com
Mailchimp	$13/mo (500 contacts)	500 contacts, 1,000 sends	mailchimp.com
MailerLite	from ~$10/mo (1,000 subs)	limited	mailerlite.com
Brevo	free daily send band (300/day)	300/day	brevo.com
Customer.io	usage-based (~$100/mo)	trial	customer.io
Klaviyo	profile-based pricing	up to 250 profiles	klaviyo.com
Postmark	from ~$15/mo (10,000 emails)	100/mo test	postmarkapp.com
Resend	usage-based	3,000/mo	resend.com

What you quietly lose when you switch

Hidden loss	Why it surprises teams	How to keep it
Automations that fired correctly for months	Their logic is invisible until a trigger stops producing sends	Export a workflow map and rebuild against the new system with test events
Revenue attribution history	Most tools cannot export historical send-to-revenue joins	Keep a data warehouse export of old campaigns
List health memory	Suppression dates drive many decisions	Export suppression tables with timestamps
Segment definitions	Internal integrations rewrite segments as different schemas	Document each segment's data source before moving
Contract credits	Unbilled balances rarely convert cross-platform	Time the exit in the last month of a term when possible

Which alternative to shortlist by departure platform

You are leaving	Because (most common)	Usually better
Mailchimp	Contact-based pricing escalates, automation feature gates	MailerLite (budget), Klaviyo (commerce), Sequenzy (SaaS billing events)
Klaviyo	Profile cost grows fast outside pure commerce	Sequenzy if you are a subscription/SaaS seller; Omnisend for lighter commerce budgets
HubSpot	Full-suite cost outgrows the email program itself	Sequenzy for billing-native automation; MailerLite for simpler programs
Any legacy ESP without clean exports	Suppression and template lock-in	Tools with REST APIs and documented export paths (e.g., Postmark, Mailgun for transactional)

Migration is a production job. The guides above keep the decision honest; the tables on this page are the summary version. Time your exit, audit the five checks, and never rely on "we can always move later" — moving is exactly what the exit-plan column exists for.

Risk table: what each alternate stack assumes about you

Shortlist	Assumes you have
Sequenzy	A subscription or SaaS product billing via Stripe, Paddle, or Lemon Squeezy; lifecycle mail that should react to billing events
Klaviyo	A commerce store with clean order/catalog data and budget for profile-based pricing
MailerLite	A simple audience model; lighter event-driven needs
Postmark / Mailgun	Developers who can own delivery events and templates; marketing lives elsewhere
ActiveCampaign / HubSpot	Sales + marketing operating as one governed contact system

A mismatch on that last column is where most failed migrations begin. The more honest question is "what does this platform need my team to keep doing?" — the guides above ask it per platform, and you should too before signing.

Billing event coverage to verify per replacement

Volume of lifecycle flows on any platform depends on which subscription events it can fire natively. Verify every row against the vendor's official documentation before switching.

Event	Question to ask
Trial start	Does the platform see the event (Stripe, Paddle, Lemon Squeezy)?
Trial end / no purchase	Does the platform stop the sending sequence cleanly?
Failed payment	Can retries generate dunning email without manual work?
Plan upgrade / downgrade	Does segmentation re-emit and re-gate automatically?
Cancellation	Does the win-back rule trigger only once, not repeatedly?
Seat added	Do team-level segments update with the account?

Any check left blank becomes "custom webhook code" — fine for a two-person team, expensive for an eight-person one. Bring these questions to pre-sales before deciding, not after migrating.

Check-first, then commit

Each alternatives guide opens with the same promise — verify against official sources — and a specific shortlist order. Use this order:

1. Read the alternatives guide for the platform you are leaving; note trade-offs you inherit.
2. Cross-check with a matchup page for the two strongest candidates.
3. Confirm pricing on each candidate's official page (linked throughout) and model your next growth milestone.
4. Only after that: run the 2-week parallel test and the five checks here.

No step can be skipped without cost; the two weeks of QA on templates and suppression alone settle most failures people blame on "bad tool".

The honest migration math

Switching platforms is mostly a schedule question, not a technology question — but only if the five checks above pass. Budget like this:

• Independent review window: two weeks with both systems live, source and destination, before cutting over.
• Billing-link rebuild window: one week per payment provider you depend on (Stripe, Paddle, Lemon Squeezy), with a documented test per subscription event.
• Template QA window: two weeks to rebuild and re-QA the highest-value templates; the rest of the archive can follow inline.
• Rollback plan: either keep the source platform sending to both streams for one billing cycle, or accept replaying events by hand if a cutover fails.

Prices on every alternatives page are decision lenses with a note to check current plans on the vendor's official pricing page — packaging changes, and the links are the source of truth.
