Quick answer
AI email marketing features may be included in a paid plan, gated behind higher tiers, limited by credits, or unavailable on some product lines. Do not compare tools only by the lowest monthly price. Check whether the AI feature you need is available for email campaigns, segmentation, automation, analytics, CRM personalization, or transactional email.
What can cost extra
| Cost area | What to check | Why it matters |
|---|---|---|
| Plan tier | Whether AI features require a paid or higher-tier plan | A tool can advertise AI while keeping useful features above entry-level plans. |
| Usage credits | Whether AI generation, summaries, or assistants use credits | Heavy campaign production can hit limits. |
| Contact/list size | Whether the plan price rises with contacts, profiles, or subscribers | AI value can disappear if list growth pushes the account into a higher tier. |
| Email/SMS volume | Whether send volume affects pricing | Ecommerce and SMS-heavy teams can pay more than newsletter teams. |
| Seats/users | Whether AI or CRM features require paid seats | CRM-led teams can face seat-based costs. |
| Automation access | Whether AI workflow support requires automation features | Drafting help is less valuable if automation is locked. |
| Ecommerce data | Whether predictive or recommendation features require ecommerce integrations | Store data can be required for meaningful AI personalization. |
| Privacy/data controls | Whether AI data use is configurable | Sensitive industries may need stricter controls. |

Choose this if

- The team has clean customer or subscriber data for personalization.
- Human review is part of the campaign workflow.
- The platform’s automation, segmentation, and analytics are already a good fit.
Skip this if
- The platform only offers generic copy help and the team needs deeper segmentation.
- AI features are locked behind a tier that is too expensive for the current list size.
- The current issue is deliverability, consent, or data quality rather than campaign production speed.
- The official feature page does not clearly state current availability.
