Manage subscriber lists and send newsletter campaigns from your server.
Manage subscriber lists and send newsletter campaigns from your server.
Manage subscriber lists, segment recipients, compose newsletters and dispatch campaigns through your own SMTP provider. Replaces the newsletter/list-management slice of the linked marketing suites, including SendGrid Marketing Campaigns and Mailjet campaigns. You supply hosting, PostgreSQL, DNS and email delivery. Not managed delivery infrastructure, full marketing automation, newsletter websites or an ad network.
Requires your own server, PostgreSQL, DNS and SMTP provider. Delivery and hosting may cost money, and provider approval is not guaranteed. You manage backups, upgrades and deliverability. No equivalent managed newsletter website, ad network, subscriber growth, MCP or AI automation suite is promised. For SendFox: manage subscriber lists, compose newsletters and send segmented campaigns through your own SMTP service. Free AGPL software has no contact-based licence fee, but server, database, domain/DNS, backups and delivery capacity are your responsibility and may cost money. SendFox already has a useful free tier. No managed deliverability, native AI writer, MCP service or complete automation parity is included.
Each comparison covers the workflow described above, rather than every paid feature.
