Hi Ser, Your tool, https://mailcheck.co/ looks amazing and the team sounds smart. However since the limits are relatively small daily ones, instead of larger monthly ones, using Mailcheck might be challenging for us. Is there any chance that you'll also be offering a monthly allocation or switching to one? Best, Samuel
Thanks for the kind words about Mailcheck! Just to clarify our daily limits are lifetime allocations for your account, not monthly resets, which makes them a much better long-term value compared to most competitors.
A: Hi! 👋 Mailcheck.co doesn’t have a native Pabbly Connect integration yet, but you can use our API with platforms like Pabbly Connect, Zapier, Make.com, and n8n to automate your workflows.
If you need help setting it up or want us to prioritize a native Pabbly integration, just let us know — we’re happy to assist! 🚀
A: We don’t offer a native integration with Constant Contact at this time, but you can easily connect it using Zapier, Make (Integromat), or n8n. These tools let you automate workflows like: → New contact added in Constant Contact → Email sent to Mailcheck for validation → Action taken based on result (e.g., update contact, stop sync)
Absolutely - we’ve already prioritized our backlog with ongoing improvements, and right now this is just a single request for a native Constant Contact integration. If we see more demand, we’ll definitely bump it up the list. Thanks for your great integration suggestion Samuel
Q: Is this meant for org use, or customers too?
Can a subscription be used to provide services to a customer base? If so, can unique API keys and Integrations be used so that usage for each customer can easily be identified.
A: Yes, Mailcheck.co can absolutely be used to serve your customers — whether you’re running an agency, SaaS platform, or internal tool. Our service is flexible and supports both organizational use and customer-facing use cases.
You can generate unique API keys for different projects or customers, allowing you to easily track usage separately. This makes it simple to monitor usage, apply rate...
Thank you for quick and detailed response. I'll have to check the product out. Please respond to my comment on deliverability to a response you provided to another question.
A: Hi! Thanks for your question. At the moment, unused monthly credits do not roll over to the next month. Each billing cycle includes a fresh allocation, and any remaining credits from the previous period will expire at the end of that cycle. Let us know if you have any other questions - happy to help!
Q: Monthly Allocation
Hi Ser,
Your tool, https://mailcheck.co/ looks amazing and the team sounds smart. However since the limits are relatively small daily ones, instead of larger monthly ones, using Mailcheck might be challenging for us. Is there any chance that you'll also be offering a monthly allocation or switching to one?
Best,

Thanks. There's always a way! Is there a reason you don't have a native integration?
