Do-not-send list
Addresses that bounced or complained. Blocked before any send, across every server in this org.

Server settings
How this server connects to a provider and which domain it sends from.
Sandbox: every message is quarantined and never reaches a real inbox. The providers below are saved but not used until Delivery mode is Live.
Used for DKIM/SPF/DMARC checks. Leave blank to derive from the From address later.
Save the server first - providers, policies and domain checks attach to it once it exists.
Attached providers
This server sends through these registered providers, listed in the order the active
policy would pick them. Credentials live on the
Providers screen - here you
only choose which ones this server uses, and how.
| # | Provider | Order | Weight | Caps (day / month) | Used (org-wide) | |
|---|---|---|---|---|---|---|
| No providers attached. Pick one below. | ||||||
Attach a provider
Order and weight are this server's own; caps belong to the provider and count across every server using it.
Distribution
Which policy decides between the providers above. Build them on the Distributions screen.
Sending providers
Register each provider account once - credentials and its allowance live here. Then attach
it to servers on Server settings;
caps count usage across every server it is attached to.
Account emails are always delivered.
Password resets, invites, welcome and verification emails to your organization admin are
carried by FlowPrime's own infrastructure (sent from FlowPrime's address) whenever your
providers can't deliver them - even before any provider is configured. Everything else
sends through the providers below, from the sender addresses you configure.
| Provider | Type | Caps (day / month) | Used | Attached to | |
|---|---|---|---|---|---|
| Loading... | |||||
Add a provider
The exact From addresses this account is verified to send. Mail from any other address is refused.
Caps are this account's allowance at the provider - usually its free tier. 0 means no
limit. They apply in every strategy, counted across all attached servers.

Distribution policies
A policy decides which provider sends and what happens when one refuses. Build it here, then select it on Server settings.

How distribution works
Each box is one provider, in the order you set. The tinted box is the one a message goes to.
Priority order
Always the lowest Order number that is available. The rest are only there as backup. Use it when one provider is simply better and the others exist to catch an outage.
Round-robin
Each send goes to whichever provider was used least recently, so volume spreads evenly. Good for sharing load and for building reputation on more than one provider at once.
Weighted split
Each send is drawn at random in proportion to Weight. Use it to move traffic gradually - send 10% through a new provider, watch the bounce rate, then raise it.
Free quota first
Providers with a cap still under it - free tiers being filled - go before uncapped (metered) ones, whatever their Order; Order breaks ties. Use it to burn free allowances (SES, SMTP2GO, Resend) before anything paid.
Caps
A daily or monthly ceiling on one provider - usually its free allowance. 0 means no limit. Caps belong to the registered provider and count across every server attached to it: the allowance is the account's at the provider, not any one server's. They apply in every strategy, not just Free quota first: a provider that has reached its cap drops to the bottom, so round-robin and weighted quietly stop choosing it. Counting is per calendar day and per calendar month, and only counts mail actually handed to that provider - blocked and suppressed messages do not use up your allowance.
Soft (default): once every provider is over its cap, sending continues on the least-bad one. You may pay for overage, but mail keeps moving.
Hard: once every provider is over, sending stops and messages fail. Choose this only when an unexpected bill is worse than undelivered mail.

When a provider refuses
Try the next provider - the message is handed straight to the next one in line, usually within the same second. This is the main reason to run more than one provider.
Leave it to the retry worker - the message is queued and retried later, which may pick a different provider by then. Slower, but it does not hammer a struggling provider.
No failover - only the chosen provider is tried, and if it refuses the message fails permanently rather than being retried through someone else. Use it when a message must come from one specific sender or not at all.
