Instantly + SalesCrew
Mirror your Instantly sender and domain registry into SalesCrew, so the accounts you warmed there sit beside the pipeline they feed. Cadences send through Instantly or through SalesCrew's own mailbox pool.

- Registry sync, read into SalesCrew
- Instantly or mailbox-pool sending
- Suppression checked at freeze and send
The short answer
- SalesCrew mirrors your Instantly registry. It reads your senders and domains, so your pool is visible and usable as configuration on the SalesCrew side.
- You pick the send provider per campaign. Instantly sends through its API, or SalesCrew's own mailbox pool sends over SMTP with per-mailbox and per-domain daily caps, cooldown stamps and suppression re-checked at send time.
- Warmup stays in Instantly, and the pipeline, inbox and replies live in SalesCrew. The two tools work side by side.
Mechanism
What each part of the connection does, and in which direction.
| What | Mechanism | Direction | Objects | Status |
|---|---|---|---|---|
| Sender and domain registry | Mirror sync from Instantly into SalesCrew | Inbound | Sender pool, sending domains | Available |

| Suppression | Enforced by SalesCrew at audience freeze and again at send | Internal | Suppression entries | Available |
Mechanisms read from the SalesCrew integration table, September 2026. Instantly's own site is the authority on its pricing and its warmup behaviour.
Setup
Sync the registry, then decide which tool actually sends.
- 1
Add the Instantly key
Settings, integrations, Instantly. The key goes into your instance's Supabase Vault and is not displayed again. The MCP twin is integration_set_key.
- 2
Run the sync
instantly_sync mirrors the sender accounts and sending domains into SalesCrew's registry, so the pool is visible where you build audiences.
- 3
Connect the reply mailboxes
Replies reach SalesCrew over IMAP from the mailboxes themselves. Without this step you will see sends but not answers.
- 4
Import the suppression list
Before any audience is frozen. Suppression is checked at freeze and again at send, so it has to exist first.
- 5
Choose the sending path
Set the provider on the campaign: Instantly, or SalesCrew's mailbox pool. campaign_set_provider is the MCP twin, and warmup keeps running in Instantly either way.
- 6
Turn cadences on in review
Cadences run on their schedule, and any agent-written step waits in the approval queue for a person to approve.
Questions
- Which tool sends my cadences?
- The provider you set on the campaign. Instantly sends through its API, or SalesCrew's own mailbox pool sends with per-mailbox caps. Either way, suppression is re-checked at send.
- Where does warmup happen?
- In Instantly or your warmup provider of choice. SalesCrew reads the warmed senders through the registry mirror and puts them to work in cadences.
- Why mirror the registry at all?
- So the accounts and domains you already manage are visible where audiences and caps are set, instead of living in a second tool nobody opens while planning a campaign.
- What does SalesCrew add beside Instantly?
- A pipeline, a shared inbox, a data bank, marketing spend in the same database, and an MCP server with 140+ tools so an agent can operate all of it.
- Which way does the sync run?
- From Instantly into SalesCrew. Your Instantly setup stays as it is.
Keep the warmup, move the pipeline
Mirror your registry, connect the reply mailboxes, and see the replies as deals rather than rows.
