Four objections every operator weighs before migrating away from ConvertKit or any SaaS. Answered without spin — these are real tradeoffs, and the right pick depends on your team.
1. "Switching costs more than it saves."
Honest assessment: at lists under ~500 contacts, the ConvertKit free or entry tier may be cheaper than running a $5–10/mo VPS plus the AcelleMail license — even before counting operator time. Break-even typically lands between 1,000 and 5,000 contacts. Run your own numbers via the cost calculator before deciding.
2. "Self-hosting deliverability will tank."
True if you run a self-managed MTA without warmup. NOT true when AcelleMail forwards through a managed sending service (Amazon SES, SendGrid, Mailgun, Postmark) — those vendors maintain IP reputation; AcelleMail only orchestrates campaigns and tracking. Reaching inbox-placement parity with ConvertKit is the norm, not the exception, with this setup.
3. "My team doesn't have time to learn another tool."
Genuine concern. The AcelleMail UI mirrors common patterns (campaign builder, audience lists, automation flows) so most ConvertKit users are productive on day one. The real time sink is rebuilding multi-step automations and template libraries — plan 1–5 days depending on complexity, not weeks.
4. "What if AcelleMail stops being maintained?"
Self-hosting flips the risk: you own a perpetual copy of the source. No vendor pricing change, deprecation, or acquisition can take the platform away. If updates stop, your existing install keeps running. Compare to SaaS where vendor decisions about pricing, features, or shutdowns are unilateral.
