Hey t= here =F0=9F=91=8B,

July = was a big month. We had a blast at Laracon, shipped a major update to the P= ostmark MCP server, and published a new guide on bulk email in Python. We'v= e also got a customer spotlight from a repair shop CRM serving shops around= the world. Let's get into it.

Shipped

The Postmark MCP server: one year later

A yea= r ago, the Postmark MCP server shipped with one useful tool: sendEmail. The= latest release has 24 tools across eight categories (sending, templates, m= essage search, delivery diagnostics, bounces, suppressions, stats, and webh= ooks). The new diagnoseDelivery tool i= s our favorite: it checks suppression status, recent message history, and b= ounce records in one call, then returns a plain-English recommendation.

Sending bulk email in Python? Prioritize practices that get yo= ur mail delivered

The D= IY Python approach (smtplib, a CSV file, a loop, and hope) all but guarante= es delivery problems. We published a guide on bulk email in Python that cov= ers what actually matters for deliverability. Read the guide=

Laracon recap

We ha= d an incredible time at Laracon in Boston. The Laravel community brought gr= eat energy, and we got to meet some amazing customers building all kinds of= projects with Postmark.

This = month we're featuring Viktor Sm=C3=A1ri, founder of Repero.m= e, a repair shop management system that serves bike shops, electronics = repair shops, and other service businesses around the world. Viktor switche= d to Postmark for reliability and easy setup, and now uses it to send invoi= ces and quotes that his customers' end customers need to receive.

How would you describe yourself in one sentence?

Softw= are Engineer who loves to build products

Can you tell us a little bit about your experience and the work= you do?

I am = a CTO and have built and helped a few startups with the full stack + the Li= nux system administration and deployments

How has Postmark helped you?

Postm= ark has saved me a lot of time when building repero.me which serves multipl= e repair shops around the world. I switched to Postmark for it's known reli= ability and easy setup. Now I sleep better knowing that my customers emails= get delivered.

How are you using Postmark on your projects today?

My cu= stomers are repair shops, and they email their end customers invoices and q= uotes and it is critical that these emails get delivered. I used Postmark's= API to make it easy for my repair shops to verify their email addresses an= d get information on how to add their DNS records for even better deliverab= ility.

What advice would you give other folks in your role about imple= menting and managing their email?

Try P= ostmark if you value your time and want to get up and running quickly!
