Time-sensitive email needs fast, predictable delivery and clear visibility when something goes wrong.
Fast, traceable transactional email with an AI copilot that explains every failure
Password resets land in spam or arrive late
Separate IP pools and monitoring keep transactional traffic away from bulk mail.
You find out about failures from customers
Webhooks and message logs show every bounce and deferral as it happens.
Marketing sends hurt critical mail
Streams and pools isolate each type of traffic so one cannot damage the other.
Send reset links and one-time codes that must arrive within seconds, on a stream kept separate from anything promotional so queues never delay them. Retries are handled safely.
Confirm purchases the moment payment succeeds, attach PDF invoices, and use idempotency keys so a retry from your backend never produces a duplicate receipt. Support can find any receipt later.
Notify users of new-device logins and credential changes, with delivery events recorded so you can show when each alert was sent and whether it bounced.
Push delivered, deferred and bounced events into your own database so support and product screens show real email status without querying a mailbox. Fewer tickets reach engineering.
Paste a bounce or deferral and get a plain-language reason, the likely cause and a suggested fix. The copilot only advises; your team applies any change to DNS or settings.
Models learn your normal delivery times per provider and flag unusual delays before users complain. You choose the thresholds and who is notified, and alerts never change routing on their own.
An MCP-compatible interface lets approved AI agents and internal tools query message status or draft sends. Scoped keys and a human approval step keep every action under your control.
Generate first drafts of receipt, reset and alert wording that match your tone. Nothing is saved or sent until a team member reviews and approves the final template.
AI features here are assistive: they suggest, summarise and flag, while your team reviews and stays in control of every sending and configuration decision. [Confirm which AI features are available at launch.]
Use different sending domains or IP pools so a campaign problem cannot slow or spam-folder password resets and receipts.
Authenticate every sending domain and check alignment with the From address, then move DMARC from monitoring to enforcement once reports are clean.
Attach a unique key per event so retries after a timeout cannot deliver the same receipt or code twice to a customer.
Stop mailing addresses that return permanent failures and alert on spikes, since repeated bounces damage the reputation of your critical mail.
Include a plain-text part, one clear action and a recognisable From name. Lean messages render everywhere and look less like phishing.
Transactional email is triggered by a single user action and delivers information the person needs, such as a receipt or reset link. Marketing email is promotional and sent to groups. Providers and regulations treat them differently, so keep them on separate streams, domains or IP pools.
Use an email API or an authenticated SMTP relay rather than your own web server. Send from a verified domain, set up SPF, DKIM and DMARC, use idempotency keys, and consume webhooks so your app knows whether each message was delivered or bounced.
Authenticate your domain, send from a consistent address, keep reset mail separate from promotions, and avoid link shorteners or heavy images. Monitor deferrals and complaints per provider so you can react quickly if one mailbox provider starts filtering your messages.
Time-sensitive messages such as one-time codes should reach the mailbox within seconds under normal conditions. Actual speed depends on the receiving provider, so track delivery times per provider and alert on delays. Keep reset links valid long enough to cope with slower providers. [Confirm delivery-time targets before publishing.]
Not always. Low-volume senders often do well on a well-managed shared pool, while higher or business-critical volume benefits from a dedicated IP you can warm and monitor. Decide based on volume, consistency and how costly a delayed message would be. [Confirm pool options.]
Yes, SMTP and API sends can include attachments such as PDF invoices, subject to message size limits. Keep files small, or link to a secure download page instead. Large attachments slow delivery, so test with real invoices before launch. [Confirm attachment size limit: [limit].]
Subscribe to webhook events for delivered, deferred, bounced and complained outcomes, and store them against your own record. The message log lets support search by recipient or message ID to see the full delivery timeline for any single email. Alert on bounce spikes too.
AI can explain bounce codes in plain language, flag unusual delays and draft template wording. It works as an assistant: your team reviews suggestions and approves any change before it affects sending. [Confirm which AI features are available at launch.]
