Email marketing on isolated sending
Your reputation is yours.
Silo runs your broadcasts, drip sequences and automations through your own Amazon SES or SMTP account. No shared pool of IPs, no shared suppression list, no one else's complaints landing on your inbox placement.
$97 once, with every feature included. You pay your sending provider directly (Amazon SES lists about $0.10 per 1,000 emails).
Why isolation matters
On a shared pool, one bad sender affects everyone on it.
Most email platforms send your mail through IP addresses and domains shared with other customers. When one of them mails a purchased list, mailbox providers see complaints and bounces coming from those shared addresses, and everyone on them feels it.
Silo doesn't pool anyone. Each account connects its own Amazon SES account or SMTP provider, keeps its own suppression list, and serves its signup pages and tracked links from its own domain. Your deliverability depends on one sending history: yours.
It also means you pay your sending provider directly, at their price, and Silo never charges per email.
A hard bounce or a spam complaint is a fact about one sender. It should never become a fact about everyone sharing the pipes.
How it works
Three steps to your own sending.
Connect SES or SMTP
Paste your Amazon SES keys or SMTP credentials. Silo encrypts them and makes a real test call before saving, so bad credentials fail now, not on your first send. For SES, one click sets up bounce and complaint reporting in your AWS account.
Add your domain and your people
Point a subdomain like
links.yourcompany.comat Silo for signup pages and tracked links. Import from Mailchimp or Kit with tags and unsubscribes intact, or start collecting signups.Send
Write broadcasts in the drag-and-drop editor, build drip sequences and automations. Every send, bounce and complaint stays inside your account.
What you get
A complete email marketing tool, without the shared risk.
Drag-and-drop editor
Build emails from blocks, start from eight starter templates, and save your own designs to reuse.
Broadcasts with A/B subjects
Send to a list, tag or segment. Test two subject lines on part of the list and send the winner to the rest.
Sequences that branch
Timed drips with merge fields, and steps that only send if someone opened or clicked the previous email.
Visual automations
Trigger on list joins, tags, API events or a yearly date. Send, wait, branch, tag, move lists or call a webhook.
Signup forms and pages
Embeddable forms and hosted signup pages on your domain, with double opt-in and a subscriber preference center.
API, webhooks, store sync
REST API and signed webhooks, Zapier-ready. Shopify and WooCommerce order and customer sync that respects consent.
Pricing
One payment. Never per email.
Every feature is included. Your sending costs go straight to your provider, at their rates.
| What you buy | Price | What you get |
|---|---|---|
| Silo Lifetime | $97 | Starter limits for life: 10,000 contacts, 100,000 sends a month (fair use), 1 sender domain and 1 tracking domain, every feature. |
Built for isolation
Your domain, your credentials, your suppression list.
Links on your own domain
Signup pages, tracked links and open pixels are served from a subdomain you own (a CNAME to Silo), never a domain shared with other accounts.
Encrypted credentials
Your SES keys and SMTP passwords are stored encrypted and tested before the first send. If they stop working, sending stops. It never falls back to anyone else's service.
Per-account suppression
Bounces, complaints and unsubscribes suppress addresses for your account only. Nobody else's list decisions reach yours.
