MCP serverLatest
v2.1.0
April 25, 2026Faster send rates for every account
Hourly send rates raised significantly across all paid accounts after infrastructure load testing. Trials send at full speed. Stale-job protection keeps deleted recipients from tripping sending service safeguards.
Improved
- Hourly send rates raised up to 5x: paid accounts now send between 25,000 and 80,000 emails per hour, up from 5,000 to 25,000
- Nonprofit accounts get the same raised rates as their standard counterparts
- Trial accounts send at 50,000 emails per hour, full paid speed
- Production worker pools rebalanced to deliver the new rates reliably
- Send speed is now published on the pricing page
Fixed
- Queued sends whose recipient was deleted are discarded cleanly instead of failing and tripping sending service safeguards
- Campaign build jobs get the same protection
- Worker timeouts raised so long-running sends complete reliably
- Internal load-testing safety gate hardened
