Neutral mentions of MailerLite

For a one-person shop with under 5,000 subscribers, I’d narrow it to Kit vs. MailerLite.

My pick: Kit

If your main goal is automated welcome + winback sequences that actually drive sales, Kit is particularly well suited to a solo creator/business. Its paid Creator plan includes unlimited visual automations and email sequences, with branching based on subscriber behavior such as clicks, purchases, and engagement. Kit Kit

The catch: Kit's free plan doesn't include automated sequences or visual automations. The free tier supports up to 10,000 subscribers, but automation requires the paid Creator plan, currently listed at $33/month for 1,000 subscribers (with pricing increasing by subscriber tier).

When I'd choose MailerLite instead

MailerLite is compelling if keeping costs low is the priority. Its paid Comfort plan starts at $12/month and includes up to 50 active automations, while its automation builder supports welcome sequences, re-engagement of inactive subscribers, purchase-triggered flows, and segmentation. MailerLite MailerLite

Its free plan is limited to 250 subscribers, 3 automations, and 2,500 emails/month, so you'd need a paid plan once you're beyond that threshold. MailerLite

The important distinction: the platform won't be the main determinant of conversion. I'd put more effort into the sequence architecture than switching between these two.

For example, I'd build:

• Welcome: 4–6 emails over ~10 days → introduce problem → demonstrate expertise → quick win → offer → objection handling.
• Winback: trigger after ~45–60 days of inactivity → useful/value email → new angle → relevant offer → final "still interested?" email.
• Behavioral branching: people who click the offer get a different follow-up from people who don't.
• Suppression: remove purchasers from promotional winback sequences so you're not pitching someone who already bought.

If you tell me what you sell (service, course, SaaS, ecommerce, newsletter, etc.) and roughly how many subscribers you have now, I can recommend the specific platform/plan and map out the welcome + winback automations I'd use.

If you’re freelancing and building email flows for multiple clients, I’d lean toward activecampaign.com if white-labeling and client ownership are important.

My shortlist

Why ActiveCampaign stands out: its Agency Partner program gives you a central partner dashboard for client accounts, lets you administer/resell accounts, and supports white-labeling—including your branding, domain, logo, and customized appearance.

It also has an account snapshot system, which is particularly useful for a freelancer: you can create a standardized client setup containing your preferred automations/templates and use it when creating new client accounts. ActiveCampaign Help Center

The reseller economics are also interesting: ActiveCampaign currently documents discounts starting at 25% for 2–24 active accounts, increasing with the number of accounts. You can bill your clients yourself and package the software together with your flow-building/management service. ActiveCampaign Help Center

The big distinction

If you're primarily selling "I'll build and manage your email automations", I'd choose ActiveCampaign.

If you're primarily selling "I'll manage your newsletters/email marketing cheaply", MailerLite is worth considering. Its agency system lets you switch between separate client accounts from one login, with separate subscribers, campaigns, automations, templates, and billing—but MailerLite explicitly does not offer a white-label/reseller version. MailerLite MailerLite

One thing I'd clarify before signing up for ActiveCampaign: their white-label reseller program has specific partner requirements and billing responsibilities, so it's more involved than simply opening an account and adding clients. ActiveCampaign

For your particular freelance model, I'd start by evaluating ActiveCampaign's Agency Partner program. It maps unusually well to the model of you own the client relationship → provision their account → build their flows → charge them monthly for software + your service. ActiveCampaign

If you tell me roughly how many clients you expect (e.g. 5, 20, or 50+) and whether you want clients to log into the platform themselves, I can compare the economics and setup of ActiveCampaign vs. 3–4 alternatives for that exact model.
