I’m building a SaaS platform where users can connect their custom domains to their online shops. I need an email service that can send transactional emails from various domains (not just one). My previous provider suddenly banned my account without explanation, so I’m searching for alternatives. The main requirement is supporting multiple sender domains since each client uses their own domain. Has anyone dealt with similar multi-domain email needs for their SaaS? What providers work well for this use case?
Been through this exact situation with my e-commerce platform. After getting burned by unreliable providers, I went with SendGrid and it’s handled our multi-domain setup without issues for over two years now. The domain authentication process is smooth and their documentation actually makes sense unlike some others. What I love most is their transparent policy enforcement - they’ll warn you before taking action rather than just shutting you down overnight. Pricing scales reasonably as you grow, and their webhook system for tracking delivery status is solid. One thing to consider is setting up proper subdomain structure from the start rather than trying to retrofit it later.
I run a multi-tenant SaaS and choosing the right email provider matters. My previous provider suspended my account without warning, so I switched to Amazon SES and it’s been great. It handles multiple domains easily, domain verification is straightforward, and you can manage everything through their API. At $0.10 per thousand emails, it’s cheap too. Watch out for the initial sending limits though—you’ll need to gradually request increases as your volume grows. Make sure you set up SPF and DKIM records properly or your deliverability will tank. I’d also grab a backup service like Mailgun just in case.
postmark’s been solid for my saas with multiple client domains. yeah, their approval process is tougher upfront, but once you’re in, they won’t randomly ban you like others. api’s clean, domain setup takes 5 mins tops. costs more than ses but saves you tons of deliverability headaches.
