Seamailer
Seamailer lets you send email campaigns, signup forms, and automated sequences without contact caps. The free Taste Breaker plan includes 12,000 emails per month, unlimited contacts, segmentation, templates, and API access from one dashboard.
Many email tools raise prices as your list grows. Seamailer advertises unlimited contacts on every plan and no daily send caps, including API sends, so list size is not the billing lever. Paid tiers mainly add team seats, branding removal, and advanced analytics rather than charging per subscriber.
Founders and small teams use it for newsletters and lifecycle automation, while developers integrate through the Seamailer API and SDK. Appetiser is $7.19 per month with two team members; Main Course is $12.59 per month with unlimited seats and dedicated priority support.
