Common questions
How long does setup actually take?
Most developers send their first email in under 5 minutes. Sign up, grab your API key, point your AI at our docs, and you're sending emails. DNS verification for custom domains takes a few hours.
Will my emails actually reach the inbox?
We automatically configure SPF, DKIM, and DMARC for your sending domains. Same authentication used by Gmail and Outlook. Our customers see 99%+ inbox delivery rates.
You're newer than SendGrid. Can I trust Ark?
We're newer, which means faster support and a team that reads every piece of feedback. Our infrastructure is built on proven providers. If something goes wrong, email [email protected] and you'll hear back from a human within hours, not days.
What happens after my free 5,000 emails?
You pay $0.50 per 1,000 emails. No monthly minimums, no tier upgrades, no surprise charges. Send 100 emails one month and 100,000 the next. Same rate, same features.
Do I need to use the MCP server?
No. Most developers use our REST API or SDKs. The MCP server with 26 tools is optional. It's useful when your AI needs to check delivery status, handle bounces, or manage suppressions directly.
