New transactional-only projects where deliverability is the only metric that matters — Postmark or Resend now dominate that mindshare.
Existing SendGrid deployments and teams that want a single bill for transactional plus marketing campaigns plus SMS (via Twilio).
Why we say this
Editorial pulled these weaknesses from SendGrid (Twilio)’s product card in our Top 10 Transactional Email Software for 2026:
- ! Verified buyer complaints across G2 2023-2024 cite deliverability score drops vs pre-acquisition baseline
- ! Support response times have degraded post-Twilio (multi-day responses reported on lower paid tiers)
- ! Enterprise/dedicated IP pricing is opaque; sales-led negotiation required
- ! At scale, roughly $0.85 per 1,000 emails — 8x more expensive than AWS SES
- ! Free tier reduced to 100 emails/day from earlier 12,000/month in 2023
- ! Twilio cross-sell pressure has pushed Email into a CPaaS-bundle narrative that not all email-only buyers want
If SendGrid (Twilio) is wrong for you, consider these instead
