We had days, not weeks or months, before the surge hit. SupportYourApp took on that challenge: launch in 7 days, one agent plus AI. It worked, and when things picked up, scaling was just as easy.

Challenges
-
A tight timeline
The traffic spike was days away, leaving no room for a lengthy hiring or onboarding process. Mailcheck needed a working support setup fast, not weeks into the surge.
-
Repetitive routine requests
Most tickets covered the same ground: pricing questions, plan limits, and how the validation process works. Answering these manually would leave little time for more complex cases once volume climbed.
-
24/7 multilingual coverage
Mailcheck's customers are located in multiple regions and log in whenever it suits them. A support team working standard hours would not be able to handle requests coming in overnight and on weekends, especially with volume about to increase. Additionally, the client needed someone that could speak several languages to communicate with customers from different countries.
Solution
SupportYourApp paired one human agent with an AI agent, launching the full setup in 7 days.
-
Fast, guided setup
Mailcheck's knowledge base, past resolved tickets, FAQs, and product documentation were fed directly into SupportResponse. The AI agent learned Mailcheck's product and tone as if it were already part of the team.
-
Autonomous resolution for routine requests
SupportResponse handled L0–L1 requests on its own, covering pricing, account setup, and how-to questions without a human agent stepping in.
-
Human hand-off for complex cases
Sensitive or complicated requests were routed straight to the human agent, so customers needing a bit more attention and help, got a person right away, without going through the AI agent first.
-
Omnichannel, multilingual coverage
The AI agent works across chats, emails, socials, and WhatsApp in 45+ languages, while SupportYourApp's team of 60+ languages made it easy to match Mailcheck with the right human agent.

Faster resolutions across the board
As Mailcheck's customer base kept growing, the setup grew with it. Two months in, SupportYourApp added two more agents to keep pace with rising volume, while the AI agent continued to handle the bulk of routine requests. The partnership shows how a small team can offer 24/7, multilingual support without adding headcount for every new region.
