SendGrid

SendGrid is a cloud-based email delivery platform, acquired by Twilio in 2019, that provides transactional and marketing email at scale over an HTTP v3 REST API and an SMTP relay. The platform spans Mail Send, dynamic transactional templates, Marketing Campaigns (contacts, lists, Segments 2.0, Single Sends), email address validation, suppression management, domain authentication (SPF/DKIM/DMARC), dedicated IP management and warm-up, subusers, Engagement Quality scoring, and detailed delivery statistics. Event data is delivered asynchronously through the Event Webhook and inbound mail through Inbound Parse. All APIs authenticate with a scoped bearer API key against api.sendgrid.com, with an EU data-residency host at api.eu.sendgrid.com. Developer documentation and the API reference are published on the Twilio documentation site.

SendGrid publishes 63 APIs on the APIs.io network, including Account API, Account State API, Alerts API, and 60 more. Tagged areas include Email, Email API, Marketing Email, SMTP, and T1.

The SendGrid catalog on APIs.io includes 2 event-driven AsyncAPI specifications and 2 Spectral governance rulesets.

SendGrid’s developer surface includes changelog, sandbox, authentication, developer portal, documentation, API reference, getting-started guide, and 85 more developer resources.

What people ask SendGrid 63

The questions people put to an LLM, and the jobs they hand an agent, that SendGrid's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sendgrid: open an issue to ask a question, or submit a pull request to add artifacts.
