Transactional Email — questions answered
Everything you need to know about transactional email with Textspeed.
Transactional email is a system-triggered message sent to a specific recipient after an action or event, such as a password reset, OTP request, invoice, order confirmation or account update. Textspeed provides transactional email infrastructure for automated, time-sensitive business notifications.
Textspeed provides API-based transactional email with templates, variables, domain authentication, event webhooks and delivery tracking. Businesses can send automated notifications from their applications and monitor accepted, delivered, opened, clicked and bounced events.
Authenticate the sending domain, configure SPF, DKIM and DMARC, create the required email templates and variables, integrate the transactional email API and configure event webhooks. Test delivery, bounce handling and template rendering before enabling production notifications.
Transactional email is triggered by a specific customer or system event and is generally expected by the recipient. Marketing email is campaign-based communication such as offers or newsletters. Keeping the streams separate helps businesses manage sending logic, relevance, deliverability and reporting.
Transactional email pricing depends on monthly email volume, sending infrastructure, deliverability requirements, API features, support and account configuration. Textspeed should provide a current quote based on the expected transactional traffic and required technical features.
Common uses include password resets, OTPs, invoices, receipts, order confirmations, account notifications, payment updates and service alerts. SaaS, e-commerce, fintech and other digital businesses can trigger these messages automatically from application events through Textspeed’s email API.
Yes. Textspeed’s transactional email page states support for SPF, DKIM and DMARC domain authentication, templates with variables and webhooks for real-time email events. These capabilities allow applications to authenticate sending, reuse message structures and receive delivery or engagement status updates.
Check domain authentication, recipient validity, API response, template variables, sender configuration and webhook events. Review bounce codes and delivery logs to identify whether the issue is a recipient mailbox, authentication problem, content rule or application integration. Correct the underlying cause before retrying at scale.
