Diversified Stack
The Diversified Stack is our recommended plan: one monthly bundle that mixes
Premium Outlook tenants,
SMTP inboxes and
Google Workspace accounts, all set up and connected for you. It comes in
three sizes: Starter, Growth and Enterprise.
Why diversify
Section titled “Why diversify”Putting all your sending on one email provider is a single point of failure. If that provider tightens its rules or your domains on it run into trouble, everything stops at once. Spreading your inboxes across three providers spreads that risk: if one has a bad week, the others keep sending.
Each inbox type also has its own strengths, so a mix lets each one do what it’s best at:
- Outlook gives you the most inboxes per domain, so it carries most of your volume.
- Google Workspace is the most widely trusted, so it’s ideal for your most valuable prospects.
- SMTP is the cheapest per inbox, so it adds extra capacity at low cost.
Inbox types compares them in detail.
The three tiers
Section titled “The three tiers”| Starter | Growth (most popular) | Enterprise | |
|---|---|---|---|
| Price | $99/mo | $399/mo | $3,499/mo |
| Sends per month | 40K | 215K | 2.15M |
| Premium Outlook tenants | 2 (2 domains) | 10 (10 domains) | 100 (100 domains) |
| SMTP inboxes | 10 (2 domains) | 100 (20 domains) | 1,000 (200 domains) |
| Google accounts | 5 (1 domain) | 30 (6 domains) | 300 (60 domains) |
| Domains you need | 5 | 36 | 360 |
| DNS and authentication setup | Included | Included | Included |
| Support | Private Slack support | Dedicated Slack support | Dedicated account manager |
One Outlook tenant is one domain with up to 100 mailboxes. Google and SMTP have 5 inboxes per domain. That’s why the domain counts add up the way they do.
Which tier fits
Section titled “Which tier fits”Pick by how many emails you’ll send a month:
- Up to 40,000: Starter.
- Up to 215,000: Growth.
- More than 215,000 but under 1 million: Growth, with a custom stack on top sized by our team.
- 1 million or more: Enterprise.
