Start free, upgrade when your list justifies it.
Practical decision framework.
MailerLite's free plan covers up to 1,000 subscribers — enough to validate your audience before spending.
Selling digital products or courses? Kit's automation is purpose-built. Need CRM and sales tracking? ActiveCampaign.
All three platforms have good deliverability, but list hygiene (removing inactive subscribers) matters more than the platform.
Upgrade only when your subscriber count or revenue justifies the next plan tier.
