02The adapter

A Connectify-owned SendGrid adapter, not a packaged connector

Connectify removes that friction by keeping the SendGrid adapter inside our own runtime, monitored by our SRE rotation and updated as Twilio ships breaking changes. That means the field maps, sync cadences, and replay rules are shaped to your exact data model — including Domain authentication automation (SPF, DKIM, DMARC) and IP warm-up scheduler for new dedicated IPs. For marketplace sellers, the difference shows up the first time the upstream API throws a 500 — the adapter retries, journals the failure, and never silently swallows a transaction.

Where SendGrid usually breaks — and how the adapter holds

The recurring tax on growth shows up as multi-channel inventory sync and fee management. Our team closes that gap by mapping every payload through a versioned schema layer with explicit lineage — every record can be traced from the SendGrid originating event down to the field that wrote it, so the warehouse team stops chasing emails. The adapter also ships with Suppression list synchronization across products so the runtime can keep up when marketplace seller crews push volume spikes during seasonal peaks.

Why Marketplace Sellers (Amazon, Walmart, eBay) pull SendGrid integration the hardest

Marketplace Sellers (Amazon, Walmart, eBay) are constantly fighting multi-channel inventory sync and fee management — and SendGrid sits exactly in the middle of that workflow. Connectify pre-maps the SendGrid entities the industry actually uses (not the entire vendor catalog) and wires Event Webhook bringing bounces and complaints into Connectify into the lifecycle that matters: serve-to-renew. That is the difference between a connector that lights up a checkbox and an adapter that so the warehouse team stops chasing emails.

Commercial terms — one flat monthly plan, no setup fee

Connectify charges a monthly retainer sized to your message volume — no per-API-call gotchas, no per-seat surcharges, and no setup fee to get started. The SendGrid adapter goes live only after it is reconciled and signed off by the team that will operate it inside the marketplace seller workflow. A one-page exit clause hands you the code if you ever leave, so Connectify keeps the adapter working across your full team to keep your business.

05FAQ

Frequently Asked Questions

  1. What does pricing look like?

    The SendGrid adapter runs on a flat monthly retainer sized to message volume — no per-API-call gotchas, no per-seat surcharges, no setup fee, and a one-page exit clause.

  2. Does it work with our existing SendGrid licenses?

    Yes — the adapter rides on top of your existing SendGrid subscription. We use service-principal or OAuth M2M credentials so the integration never burns a named-user seat and never pushes you into a higher tier.

  3. How long does the SendGrid integration take to ship?

    Our standard window is thirty days from signed scope to live SendGrid adapter in production, plus a one-week monitored stabilization phase. For Marketplace Sellers (Amazon, Walmart, eBay), that includes a sandbox loop with your team, parallel-run reconciliation, and a documented runbook handed to your operations lead.

  4. Can the SendGrid adapter handle our custom fields?

    On first connection the adapter discovers every custom field, custom object and custom workflow inside your SendGrid tenant and presents them as first-class mappings — you decide which to mirror, which to ignore, and which to enrich.

  5. Is this a packaged SendGrid connector or a custom build?

    It is a Connectify-owned adapter, not a third-party packaged connector. We maintain the code, we monitor the runtime, and the fields, hooks, and reconciliation rules are shaped to your exact data model — not a generic schema we hope matches.

  6. How is data security handled?

    Tokens and credentials live inside a hardware-backed secret store with audit logging on every read. The SendGrid adapter runs on isolated workers with deny-by-default egress, and every message is replayable from a tamper-evident journal for downstream forensics.
