Transactional email that delivers reliably requires more than an SMTP server.
SendGrid integration for transactional email — with domain authentication, deliverability configuration, dynamic email templates, and the webhook handling that tracks email events. We implement SendGrid for applications that need reliable email at volume.
Application sending transactional email via SMTP or Nodemailer with poor deliverability — emails going to spam, no delivery tracking, and no template management
Sending email from an application requires more than an SMTP connection. Deliverability — whether the email reaches the inbox — depends on infrastructure configuration that most development tutorials don't cover:
Domain authentication. SPF, DKIM, and DMARC records must be configured on the sending domain. Email from unauthenticated domains is routed to spam by Gmail, Outlook, and other providers. This is DNS configuration work, not code.
IP reputation. Shared IP pools (used by free tiers and some paid tiers) carry the reputation of all senders on the pool. One bad actor on the shared pool can affect deliverability for all senders. Dedicated IP addresses avoid this but require volume to warm up.
Bounce and spam management. Email providers penalize domains that send to invalid addresses (hard bounces) or that users mark as spam. SendGrid handles bounce and unsubscribe management via webhooks — but only if those webhooks are implemented and acting on the events.
Resend vs. SendGrid. Resend is the modern choice for most new applications. It has a developer-first API, native React Email template support, and better debugging tools. SendGrid is the choice when: the organization already has a SendGrid account, marketing and transactional email need to be in one platform, or existing SendGrid templates need to be integrated.
SendGrid integration with authenticated domain, dynamic templates, reliable delivery, and webhook-based event tracking for opens, clicks, and bounces
Domain authentication
SPF, DKIM, and DMARC configuration. SendGrid domain verification. Sending domain configuration.
Dynamic templates
SendGrid dynamic template creation with Handlebars template language. Template versioning.
API integration
`@sendgrid/mail` npm package. Route Handler for triggering sends. Environment variable configuration.
Webhook handling
Inbound webhook endpoint for email events (delivered, opened, clicked, bounced, spam reported). Bounce list management — suppressing future sends to bounced addresses.
Unsubscribe management
One-click unsubscribe link implementation. Suppression group configuration.

Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Email integration scope is defined by the email types and the template requirements. Fixed price.

Questions, answered.
Resend for new applications. Better DX, native React Email templates, simpler API. SendGrid when: existing platform investment, marketing email needs (SendGrid has full marketing email features), or when volume-based pricing makes SendGrid more cost-effective at scale.
Resend has a native sandbox mode. For SendGrid, use Mailhog or a test SMTP server locally. Resend makes local testing easier, which is one reason to prefer it for new projects.
Part of the application build. Transactional email from $25k. Fixed-price.
