Reloop vs Mailchimp
Mailchimp owns small-business marketing email. Reloop is for product teams that need campaigns and transactional sends with APIs—not audience-based bills.
Mailchimp prices by how many contacts you store—not how many emails you actually send. That model works for newsletters with huge lists and infrequent sends. It punishes API-driven products that email active users often but don't need to pay for dormant contacts.
Transactional email (Mandrill) was historically a separate product—and still feels bolted on. Reloop charges by send volume, exposes everything via API, and includes campaigns without a separate SKU.
Audience pricing vs send pricing
Why developer-led products feel Mailchimp bills.
Mailchimp model
10,000 contacts on a free or starter tier—even if only 500 receive monthly mail—can force an upgrade. Engineering-triggered sends often require Mandrill or a third integration.
Reloop model
3,000 emails free, then tiers by monthly sends (50k, 250k, custom). Store contacts for segmentation without audience-based surcharges. See pricing details.
