SendGrid

SendGrid (now part of Twilio) is the email delivery platform we deploy for businesses that need reliable, high-volume email with full programmatic control. Unlike marketing-first email platforms, SendGrid excels at transactional email (receipts, notifications, password resets) and programmatic marketing email where the sending logic lives in your automation workflows rather than in the email platform itself. We build SendGrid implementations that handle both transactional and marketing email with proper stream separation, deliverability engineering, and real-time analytics.

Transactional email architecture is where SendGrid shines. We implement dynamic templates with Handlebars syntax for personalized transactional messages — order confirmations that pull line items and totals from your order system, appointment reminders with specific date/time and location, invoice deliveries with payment links and balance details. Each template category gets its own sending domain and IP pool to isolate reputation — a deliverability problem with marketing emails won't affect your critical transactional messages. We configure event webhooks that track opens, clicks, bounces, spam reports, and unsubscribes in real time, feeding this data into your analytics and automation systems.

Deliverability engineering prevents the most common email failure: messages landing in spam. We configure authenticated sending domains with SPF, DKIM, and DMARC alignment, manage dedicated IP warm-up schedules for new senders (gradually increasing volume over 2-4 weeks), implement engagement-based sending that throttles delivery to unengaged recipients, and build list hygiene automations that process bounces, complaints, and unsubscribes in real time. For businesses migrating from shared-IP email services, we plan and execute the transition to dedicated IPs with monitoring at every step. Deliverability dashboards track inbox placement rates, sender reputation scores, and per-ISP delivery metrics.
