You will get Custom CRM & email marketing automation with SendGrid
Project details
Hi, I'm Andy — a senior full-stack developer with 25+ years of experience. I recently architected and built an entire
in-house marketing CRM that fully replaced HubSpot for a retail company: contacts, dynamic segmentation, multi-step
email automation, A/B testing, suppression/bounce handling and analytics dashboards.
I can help you:
• Set up SendGrid — dynamic templates, sending, and event tracking (opens / clicks / bounces / unsubscribes)
• Build automation workflows — welcome series, re-engagement, abandoned-cart, post-purchase, date-based
• Build a segmentation rule engine to target contacts by behaviour, orders, status or custom fields
• Add double opt-in forms, preference centers and GDPR-compliant unsubscribe
• Build a full custom CRM so you stop paying monthly SaaS fees
Stack: ASP.NET Core, C#, SendGrid API, SQL Server. Clean, documented, production-ready code.
Message me before ordering so I can confirm scope and timeline for your project.
