About the Company

Mailcheck is an email verification platform that helps businesses validate mailing lists, remove invalid addresses, and improve email deliverability. Companies use Mailcheck's tools and API to clean their lists and boost sender reputation before running campaigns. Mailcheck had a major promo campaign scheduled that was expected to drive a sharp spike in new sign-ups within days. Their small team needed 24/7, multilingual support live before that traffic hit, not weeks later. They turned to SupportYourApp to build a support setup fast.

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.

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.
