Bird's dashboard now has broadcasts. Pick a stored audience and a published email template, and Bird resolves the audience's current members into a recipient list at send time, so reaching everyone in it takes naming the audience rather than listing addresses yourself.

Getting started

• Broadcasts
• Audiences

What's available

• A three-step composer: pick the audience and sender in Recipients, the published template in Content, and the category, tracking, and tags in Review. Submitting only ever creates or saves a draft; sending is a separate, explicit step.
• Send now or schedule ahead: schedule up to 365 days out, and reschedule a scheduled broadcast right up until it starts sending.
• Per-broadcast delivery tracking: recipients, sent, delivered, bounced, complained, opens, and clicks on the broadcast's own detail page, plus a per-recipient timeline and event view.
• Clear failure reasons: a failed broadcast names why on its detail page, from an empty audience to a template that no longer renders, so you know what to fix before you resend.

Broadcasts is a dashboard feature today, with no public API, CLI, or SDK surface.

Agent Mailboxes give your AI agents a durable email address they can own, read, and reply from. Every inbound message lands in a conversation thread with parsed body text and attachment metadata; your agent reads it and replies in one API call. No mail server to run, no domain to verify.

Claim an address. Omit the local part and Bird generates a unique address (abc123@inbox.ai) at no extra cost. On paid plans you can choose your own handle (support@inbox.ai) up to your plan's allowance, or use your own inbound-enabled domain. Each mailbox has a receive policy (open, replies_only, allowlist, drop), per-sender allow/block rules, and a 30-day retention window.

Read conversations. Inbound mail groups into threads automatically. Each message carries quote-stripped extracted_text — the new content only, without the history your agent would otherwise have to parse. Threads have placement labels (inbox, archive, spam, blocked, plus any custom label), unread state, and a last_direction field so your agent always knows whether the last move was theirs.

Reply and compose. Reply to a message in one call — the reply folds into the existing thread and sends from the mailbox address. To start a fresh outbound conversation, compose from the mailbox; the response carries a thread ID for tracking replies.

Webhooks. Subscribe to email_mailbox.message_received, email_mailbox.thread_created, email_mailbox.message_sent, email_mailbox.message_delivered, and email_mailbox.message_failed. Only inbox-placement mail fires webhooks — spam and blocked mail is stored silently.

Getting started

Create an API key in the dashboard — under the Email group, enable the mailbox scope, then follow the Agent Mailboxes quickstart to claim an address, receive your first message, and send a reply in under five minutes.

You can now deliver one-time passcodes over WhatsApp, alongside SMS and email. WhatsApp OTPs are sent from the shared Bird Authifly sender — the same "Authifly" brand you already see on our shared email sender — using the built-in authentication template, so there's no template or sender setup required. Support for your own dedicated senders is following shortly.

What's new

• Enable WhatsApp per country from the Verify → Countries settings in the dashboard.
• Automatic failover: if the primary channel can't deliver, Verify falls back through your configured channels before giving up.
• API & SDK: whatsapp is now a valid value for a verification's channel, and country routes accept a whatsapp key in their per-channel settings. This is additive — no breaking change.

Default routing change

Existing phone verifications now default to SMS → WhatsApp → email: SMS stays primary, with WhatsApp as an automatic fallback before email. Countries you've already customized are left untouched.

WhatsApp lifecycle events are no longer poll-only. Subscribe to any whatsapp.* event type from the dashboard's Webhooks page or with POST /v1/webhooks, and Bird pushes the same accepted, sent, delivered, read, and failed events you'd otherwise fetch from GET /v1/whatsapp/messages/{message_id}/events. Each delivery carries whatsapp_id, workspace_id, the message direction, from/to addresses (phone number and/or Meta business-scoped user ID), and the tags and metadata from the original send; failed messages include an error object with a Bird-stable failure code. See WhatsApp events.

Also in this release:

• Inbound email messages (get, list) now return an authentication field (pass, fail, or unknown) giving a single verdict on whether the sender's identity was verified, alongside the existing SPF/DKIM/DMARC flags.
• New guide: Plan changes & renewals spells out exactly when plan upgrades, downgrades, and cancellations take effect, and the day-by-day sequence for a failed renewal payment. It also documents that overage on paid plans is capped at 5x your plan's included email volume per period, with sends rejected past that ceiling until the period resets; the Free plan has no overage at all.

Bird Verify is now available to every workspace. Send a one-time passcode and confirm the code your user enters in two API calls — no sender to register, and no verification id to store.

Getting started

• Verify your first customer
• Verify overview
• Sending verifications

What's available

• Send and check: start a verification with POST /v1/verify/verifications — which also resends after the cooldown — then confirm the code with the check endpoint. A code can be checked once.
• Email and SMS with failover: pick the channels and their order; if the first channel can't deliver, Verify falls back to the next one on the same code budget.
• Per-country configuration: set channel availability and order, per-country senders, and a verified-domain email sender — a per-workspace overlay on Bird's per-country base.
• Built-in safety: code length and lifetime, maximum attempts, resend cooldown, and per-recipient and per-workspace rate limits, all configurable.
• Everywhere you build: the Verify API, the dashboard (onboarding, verifications log, countries, and configuration), the bird verify CLI, the Bird MCP server, and the Go, TypeScript, and Python SDKs.

More is on the way — WhatsApp and voice channels, dedicated senders, and customer-authored templates among them.
