The Bulk API is now available, we completed a major = infrastructure migration under the hood, and we're heading to Portland next= month for MicroConf. Plus, a customer story about how Postmark saved a bus= iness overnight. Let's get into it.=20 **Shipped** https://postmarkapp.com/bulk-api Bulk API is now available= =20 As we mentioned earlier this month, the Bulk API is here. Define your messa= ge content once, pass a list of recipients, and Postmark compiles and deliv= ers the individual messages on our end. One API call, thousands of emails, = and dramatically smaller payloads. We'll even handle send-speed optimizatio= n so your messages land in the inbox.=20 It's available to all Postmark customers! Just contact our support team htt= ps://postmarkapp.com/contact to get it enabled for your account, then check= out the API documentation https://postmarkapp.com/developer/api/bulk-email= to get started.=20 Already using it? We'd love your feedback.

The result? Faster queue processing, improved del= ivery performance across major inbox providers like Gmail, Yahoo, Microsoft= , and Apple, and a foundation that gives us more flexibility to keep improv= ing things.=20 Read the full story on our blog https://postmarkapp.com/blog/we-migrated-ou= r-email-infrastructure-to-kumomta-heres-why-it-matters-for-you=20 **Customer spotlight** https://100hires.com/ This month we're featuring = Alex Kravets, CEO of 100Hires https://100hires.com/, an applicant tracking = system featured by Forbes as the best ATS for SMBs and startups. When their= previous email provider shut them down overnight, Postmark got them back u= p and running the same day. Here's his story.=20 How would you describe yourself in one sentence?=20 CEO of 100Hires, an applicant tracking system featured by Forbes as the bes= t ATS for SMBs and startups=20 Can you tell us a little bit about your experience and the work you do?=20 I'm the founder and CEO of 100Hires, an ATS (Applicant Tracking System) tha= t helps recruiting teams manage candidates, schedule interviews, and collab= orate on hiring decisions. We serve thousands of teams worldwide, and relia= ble transactional email is the backbone of our product.=20 How has Postmark helped you?=20 Postmark literally saved our business overnight. Our previous email provide= r =E2=80=94 a large, well-known competitor =E2=80=94 automatically disabled= our account without warning over a routine address change. Thousands of ou= r users suddenly stopped receiving interview invitations, candidate notific= ations, and password resets. For an applicant tracking system, that's a com= plete service outage. We integrated Postmark and had emails flowing again t= he same day. Since then, we've never had a single deliverability issue. Pos= tmark gave us back the peace of mind that our most critical infrastructure = just works.=20 How are you using Postmark on your projects today?=20 Postmark is the backbone of all transactional email at 100Hires. We send in= terview scheduling notifications, candidate status updates, team collaborat= ion alerts, password resets, and account confirmations =E2=80=94 all throug= h Postmark. We've built a deep integration: we use Postmark's webhooks to t= rack deliveries, bounces, opens, and spam complaints in real time. We have = automated systems that detect inactive addresses flagged by Postmark and cl= ean them from our database. We also run delivery monitoring that alerts us = to any bounce or complaint patterns. It's not just "plug in and send" =E2= =80=94 Postmark is deeply woven into our product's reliability layer.=20 What advice would you give other folks in your role about implementing and = managing their email?=20 Two things. First, never rely on a single email provider for mission-critic= al transactional email =E2=80=94 we learned this the hard way when our acco= unt was disabled out of the blue. Always have a backup integration ready to= switch to. Second, choose a provider whose entire business is transactiona= l email, not one where it's a side feature next to marketing campaigns. Pos= tmark's focus on deliverability and their developer-friendly API made our e= mergency migration possible in hours, not weeks. Also, invest in webhook in= tegration from day one =E2=80=94 tracking bounces and complaints proactivel= y saves you from finding out about delivery problems from angry users.=20 Built something cool with Postmark lately?

Our previous email provider =E2= =80=94 a large, well-known competitor =E2=80=94 automatically disabled our = account without warning over a routine address change. Thousands of our use= rs suddenly stopped receiving interview invitations, candidate notification= s, and password resets. For an applicant tracking system, that's a complete= service outage.

We send intervi= ew scheduling notifications, candidate status updates, team collaboration a= lerts, password resets, and account confirmations =E2=80=94 all through Pos= tmark.

First, never rely on a single email provider for mission-critical tr= ansactional email =E2=80=94 we learned this the hard way when our account w= as disabled out of the blue. Always have a backup integration ready to swit= ch to. Second, choose a provider whose entire business is transactional ema= il, not one where it's a side feature next to marketing campaigns. Postmark= 's focus on deliverability and their developer-friendly API made our emerge= ncy migration possible in hours, not weeks.
