- After Mailgun's $59 surcharge per dedicated IP (which customers will need, given your shared pool deliverability record), you'll find SendGrid's high volume prices scale pretty closely.
- We do offer plans without subuser management and whitelabeling. That's so we can be a cost-effective choice for startups and low-volume senders, which I'd argue is a good thing! Pro customers always get every feature we have to offer, including a dedicated IP.
- Overages rarely happen. In the specific case he's describing, it's nearly always going to make sense to pay $10 for 60,000 more emails.
- All paid accounts are given unrestricted access to all Mailgun features. Sendgrid feature gates by plan
- Mailgun has no punitive overages, with Sendgrid you’ll pay as high as $1 per 1000 emails for exceeding your plan. https://sendgrid.com/mkt/assets/pdfs/1-16_SendGrid_Compariso...
