About PowerMTA.in
PowerMTA.in started as a personal knowledge base for running bulk email infrastructure — and grew into a free resource for Indian marketers who'd rather learn from someone doing the work than another generic listicle.
PowerMTA.in was started in 2025 by an Indian digital marketer who spends most days configuring PowerMTA servers, warming up IPs, and troubleshooting deliverability for real email campaigns — not writing about marketing theory from the sidelines.
The site began as a place to document working setups: PowerMTA configuration on OVH VPS, MailWizz and Sendy integrations, DNS records that actually pass DMARC alignment, and subject lines that move open rates in practice. Over time it expanded into broader guides on SEO, free marketing tools, and online business for Indian readers — but the standard stayed the same: publish what actually works, tested on real campaigns and real Indian audiences, not recycled from someone else's blog.
We built our free tools — including the SPF, DKIM and DMARC generators and the subject line tester — because we needed them ourselves and couldn't find versions built with Indian ESPs and use cases in mind.
PowerMTA.in is free to use, with no paywalls or paid memberships. We support the site through two transparent channels:
Display advertising via Google AdSense, and affiliate commissions through the Amazon Associates Program when you click product links on our Deals page or within articles — at no extra cost to you. Our editorial picks and guides are not influenced by which products carry an affiliate link. Full details are in our Privacy Policy.
