Solutions / SaaS & Product Email
Protect the email your product depends on.
SaaS companies send everything: onboarding, lifecycle, invoices, alerts, digests, campaigns. Usually from one account with one reputation bucket. When the marketing side has a bad week, the product side pays for it. We separate the streams and protect each one.
The context
Why this is harder than it looks.
Every SaaS company eventually re-learns the same lesson: mailbox providers score senders, not message categories. If your lifecycle campaigns, your invoices, and your password resets all leave from the same IPs under the same domain reputation, they share one fate. A complaint spike on a re-engagement campaign raises the spam-foldering odds of your receipts. Not because receivers are unfair. Because, to them, it is all one sender behaving badly.
The structural fix is stream separation: distinct sending identities per traffic class, each warmed, monitored, and rate-shaped on its own. Most teams know this in theory. Few have the infrastructure to do it properly, because it multiplies everything: DNS records, DKIM selectors, warmup schedules, monitoring scopes. That multiplication is exactly what our platform absorbs. Streams become a configuration choice, and the operational overhead becomes ours.
The second SaaS-specific risk is the compromised or runaway sender. A leaked credential, a misconfigured integration, or a bugged cron job can emit tens of thousands of messages before a human notices, and the reputation damage outlasts the incident by months. Containment has to live at the infrastructure layer: per-sender rate gates that hard-stop an outbreak at the door. A dashboard alert that hopes someone is awake does not count.
Your challenges
What this looks like from where you sit.
Marketing volume hurt your domain reputation, and suddenly password resets started landing in spam. Two teams, one shared fate.
A compromised account or a bugged integration once blasted thousands of messages before anyone noticed, and the reputation hangover lasted a quarter.
You’ve outgrown a single provider account, but the migration (new IPs, new warmup, new DNS) keeps getting deferred because nobody owns it.
Engineering owns email by accident. Deliverability gets monitored by "did anyone complain this week?"
Support cannot answer "did the invoice send?" without filing an internal ticket.
How Egressif helps
What changes when one team owns the outcome.
Streams kept structurally apart
Product email, lifecycle email, and campaigns run on separate sending identities with separate reputation: separate DKIM-signed subdomains, separate capacity, separate monitoring. One stream’s incident stays that stream’s problem.
Outbreak containment at the gate
Per-sender hourly caps hard-stop a compromised mailbox or runaway integration at the delivery layer. The incident is contained to its budget. Your domain reputation never finds out.
Warming without project management
New identities and capacity ramp automatically. Daily ceilings grow with cleanly used volume and step back on negative signals. Migrations and scale-ups stop being reputation gambles.
API-first operations
Domains, mailboxes, and routing are provisioned programmatically, and delivery events stream back via webhooks. Email infrastructure becomes a managed dependency instead of a side quest.
Continuous monitoring with humans attached
Bounce classifications, deferral patterns, blocklist exposure, and authentication health are watched per stream. Systems first, our deliverability team second. Degradation gets caught while it is still invisible in your aggregate stats.
Per-message answers for support
"Did the invoice send?" becomes a one-lookup answer with evidence: accepted by which receiving server, when, over what TLS, with what response code.
The problem
A quarterly announcement campaign triggered a complaint spike. Within days, onboarding emails were going to spam, trial conversions dipped, and the postmortem concluded (correctly, and uselessly) that marketing and product email shouldn’t share reputation.
With Egressif
On Egressif, the campaign ran on its own identities. The complaint spike raised alerts on that stream, our team intervened on cadence and list hygiene, and the campaign reputation took the hit it had earned. Onboarding mail, on its own clean identity, never noticed.
