The trade-offs
Strengths and Limitations
Dotdigital
Strengths

- Named AI agents: a Segment Agent for audiences and a Content Agent inside EasyEditor
- A Marketing MCP server connects the account to ChatGPT, Claude and Gemini
- Deliverability covered by dedicated IPs, SPF, DKIM and DMARC and a warm-up onboarding team
Limitations
- No published pricing: contact-based billing is quoted case by case
- A contact is billable as soon as it is marketable on any single channel, even if suppressed on the others
Twilio SendGrid
Strengths
- Transactional and marketing email on one account, so both build the same sender reputation
- Deliverability tooling included: dedicated IPs, domain authentication, SPF, DKIM and DMARC, plus inbox rendering and spam tests
- SDKs for Python, Ruby, Go, PHP, Java, C# and JavaScript, alongside SMTP relay and event webhooks
- Real-time and bulk email address validation
Limitations
- Email only, other channels mean buying a separate Twilio product
- Automation in Marketing Campaigns requires the Advanced plan
- The free offering is a 60-day trial, not a standing free tier
- Two separate price ladders to compare, one per product
