Qui contrôle la pile d'envoi ?

Resend : pools d'IP gérés

Resend offers dedicated IPs as an add-on on its Scale plan. Its managed dedicated IP pools handle automated warm-up, capacity scaling from inbox-provider feedback, and reputation monitoring.

Resend abstracts away the individual IP addresses inside those managed pools, automatically adding or retiring IPs as your sending volume shifts.

Bird : infrastructure et réputation

Bird runs its own global sending infrastructure and develops the underlying MTA software, including PowerMTA for on-premises sending. Bird acquired SparkPost in 2021, and its network delivers roughly 40% of the world’s commercial email.

Manage shared IPs, named dedicated IPs, and custom IP pools with automated warm-up and shared-pool overflow. Bird’s Momentum MTA adapts delivery rates per mailbox provider in real time and automatically suppresses hard bounces and spam complaints to protect your sender reputation.

Comment gérez-vous un résultat d'envoi ?

Both examples branch on returned data and error values rather than wrapping the send call in a try/catch block. Bird’s SDK throws typed errors by default and includes an explicit result-tuple mode when you prefer handling errors as values.

Resend

send.ts
import { Resend } from "resend";

const resend = new Resend(process.env.RESEND_API_KEY!);

const { data, error } = await resend.emails.send({
  from:    "onboarding@yourdomain.com",
  to:      ["customer@example.com"],
  subject: "Your March invoice",
  html:    "<p>Attached.</p>",
});

if (error) console.error(error.message);
else console.log(data.id);

Bird

send.ts
import { BirdClient } from "@messagebird/sdk";

const bird = new BirdClient({ apiKey: process.env.BIRD_API_KEY! });

const { data, error } = await bird.email
  .send({
    from:    { email: "onboarding@yourdomain.com", name: "Acme" },
    to:      ["customer@example.com"],
    subject: "Your March invoice",
    html:    "<p>Attached.</p>",
  })
  .safe();

if (error) console.error(error.message);
else console.log(data.id);

Qu'est-ce qui change autour de l'appel d'envoi ?

Un agent peut-il recevoir et répondre aux e-mails avec l'un ou l'autre fournisseur ?
Yes. Resend supports inbound email receiving, attachments, and threaded replies, and exposes received messages through its MCP server. Bird’s agent mailboxes add first-class inbox provisioning, automatic thread grouping, quote-stripped reply extraction, and sender allowlists so blocked mail never wakes your agent.
Que se passe-t-il si une tâche de réessai reprend le lendemain ?
Resend’s 24-hour idempotency window deduplicates retries across a full day. Bird retains completed send responses for 3 hours to cover network timeouts and queue retries; if your job scheduler retries failed tasks the next day, check your own database record before submitting a new send call.

Pour chaque volume inclus chez un concurrent, le besoin de trésorerie mensuel estimé de Bird correspond au plus élevé entre le dépôt du forfait payant et l'usage transactionnel à son tarif publié.

Comment comparer les coûts d'envoi d'e-mails ?

Que comprennent les lignes tarifaires de Bird et de Resend ?
The tables compare the monthly cash outlay on Bird at each send volume against Resend’s published tiers. Bird’s figures read live from our pricing catalogue, while Resend’s figures link directly to their pricing page with the verification date. Check the billing cadence, included send allowances, and add-on fees before selecting a tier. Resend lists overage rates and dedicated-IP add-ons separately from its base monthly plans.

Coût de migration

Qu'implique une migration depuis Resend ?

Moving from Resend to Bird takes four steps: swap the SDK send call, publish Bird’s DKIM and return-path DNS records alongside your existing records, import your suppressed addresses so you never email bounced or unsubscribed recipients, and update your webhook signature check.

Our migration guide maps every request field and delivery event between the two APIs. Verify your webhook handlers in Bird’s mail sandbox before switching production traffic, and schedule an automated warm-up window if you are moving onto new dedicated IPs.

Bird vs Resend : questions fréquentes

Puis-je conserver mes modèles React Email en passant à Bird ?
Yes. Your components stay exactly as they are: as shown in the Bird migration guide, you render your React Email component to an HTML string in your application and pass that markup to Bird’s send call, rather than relying on Resend’s Node SDK to render the component internally.
