7. Frequently Asked Questions
What is the main pricing difference between transactional and marketing email APIs?
Transactional emails (password resets, order confirmations, receipts) require immediate sub-second delivery and dedicated high-reputation IP pools, typically priced per 1,000 sent emails. Marketing emails (newsletters, promotional broadcasts) are sent in large batches, often priced by contact list size or higher per-thousand rates with visual template builders and campaign management tools.
When should I purchase a dedicated IP address?
A dedicated IP is recommended when sending consistently over 100,000 emails per month. A dedicated IP isolates your sender reputation entirely from other senders, preventing third-party spam spikes from hurting your inbox placement. For lower or sporadic volumes, high-reputation shared pools (like Postmark or Resend) generally deliver better inbox rates than an un-warmed cold dedicated IP.
Why is Amazon SES so much cheaper than Postmark, SendGrid, or Resend?
Amazon SES operates as raw cloud infrastructure at $0.10 per 1,000 emails with zero managed features. Specialized providers like Postmark ($1.25/1k), Resend ($0.40/1k), and SendGrid ($0.25/1k) bundle deliverability monitoring, automatic IP pool warm-up, visual template designers, webhooks, React Email SDKs, and 30–45 days of searchable message logs.
How does European data sovereignty affect email API choices?
Under EU GDPR, sending personal data (email addresses, message contents) through US-headquartered clouds can expose companies to CLOUD Act compliance issues. Providers like Brevo, Scaleway, and Mailjet maintain primary datacenters in France and Germany with strict European data isolation and ISO 27001 compliance.
Do email API free tiers renew every month?
Yes, Brevo provides 9,000 emails/month (300/day), Resend offers 3,000 emails/month, Scaleway provides 10,000 free emails/month, and AWS SES provides 62,000 free emails/month for applications hosted in EC2. Postmark and SendGrid provide one-time trial allowances (100 emails) before paid tiers apply.
How does currency conversion work in this comparison calculator?
Vendors priced natively in Euros (Brevo, Scaleway, Mailjet) are normalized using the fixed benchmark conversion rate of 1 EUR = 1.08 USD when viewing in USD, or converted from USD to EUR when viewing in EUR. Both native currency breakdowns and normalized totals are displayed transparently in each vendor card.
