Bellum — mass email at scale.
Bellum is our own mass-email platform: authenticated, high-deliverability sending at volume on Amazon SES, with segmentation, double opt-in and the event-level analytics to prove exactly what landed.
Sending at volume is easy; landing in the inbox is not. Misconfigured authentication, poor list hygiene and unmonitored bounces quietly route your mail to spam — and you only find out when the numbers fall off. Off-the-shelf tools cap out, lock your data in, or price by the contact.
Bellum sends through Amazon SES with AWS Batch doing the heavy bulk-send work and Lambda handling scheduling and event ingestion. Every open, click, bounce and complaint flows back through SES → SNS → Lambda into per-event tables, so reporting is exact and suppression is automatic. SendGrid and Azure Communication Service are available as alternate engines.
What Bellum does
Campaigns & scheduling
Drafts, HTML + plain-text bodies, per-campaign sender and reply-to, scheduled or stopped on demand, with master-campaign grouping.
Lists & segmentation
Multiple lists, CSV import, custom fields and saved segments built in a visual query builder.
Merge tags
Per-list custom fields used as personalization tags with fallbacks — [name, fallback=there].
Event-level analytics
Opens, clicks, deliveries, bounces, complaints and rejects captured per recipient via SES + SNS.
Deliverability & hygiene
SES identity verification, automatic bounce/complaint suppression, blocked-domain lists and bulk address validation.
Subscribe & consent
Public double opt-in subscribe, confirmation and one-click unsubscribe flows handled out of the box.
Campaign event data feeds straight into BI and predictive models.
