About K1W

Five people, one project queue, since 2018

K1W is not a registered PT or CV — we're an independent freelance team that has worked together as a fixed group since 2018. We're hired per project, the way a lot of Indonesian digital work actually gets done, by individuals, SMEs (UMKM) and larger businesses alike.

How we got here

We started building websites and small business tools in 2018. Over time, more clients started asking the same follow-up question after launch: why don't my emails arrive? That pulled us into email infrastructure — authentication, list hygiene, and eventually routing mail across multiple providers (currently OVH and Linode, with Amazon SES being added as an additional route) so delivery doesn't depend on any single provider's reputation.

Every email we route on behalf of a client — whether it's a password reset or a marketing send — goes through the same screening step first. That's not a policy we wrote for a review form; it's the actual reason a second and third provider became necessary: a flagged sender on one provider shouldn't take down delivery for everyone else.
