Hi Hunters!
I'm Kristyna, maker of Sidemail. I'm happy to share with you what we've been building.
We built Sidemail because sending emails from a SaaS app was way harder than it should be.
Sidemail changed that.
It's perfect for busy developers and teams that want simple and reliable deliverability without the bloat.
You'll now enjoy:
- Easy-to-use email API for sending password resets, receipts, etc.
- Messenger for writing product updates & newsletters,
- Email automations for onboarding & lifecycle flows,
- Simple integration (done in <30 minutes),
- Industry fastest email delivery,
- Reliable infrastructure,
- No-code editor and battle-tested premade email templates,
- Developer-focused features like detailed API logs, Markdown emails, simple domain verification and DKIM, and more.
If you have any questions or thoughts to share, please do tell! We're used to working with customers and are always happy to improve the platform further.
Thank you!
Kristyna 💙
Are there built-in tools for warming up new email accounts? Do the emails land in the inbox or the promotions tab?
Congratulations @k_vrbova and @pkrupar! 🎉 The Markdown email support on Sidemail is impressive, especially how intuitive it felt exploring your beautiful templates with dark mode support right out of the box. Curious—what inspired this developer-focused design choice? The one-click Stripe integration is also brilliant for automating customer email imports. Wishing you tons of engagement and feedback today!
Love the all-in-one approach for SaaS email! As a UI/UX designer, I'm curious: how did you design the workflow to balance power-user features with simplicity for teams just getting started? That tension between "all-in-one" depth and ease-of-use is fascinating in email tools. Congrats on v2.0!
I'm trying to use my own email now. I feel if they have an integration that can be powered by natural language, it can be even better.
Very clean and clear product. I'm also wondering how's it different from the Superhuman?
Looks like a great feature. I'm also wondering how's it different from the Superhuman?
As a budget-conscious startup, how does Sidemail's pricing and feature set compare specifically against established competitors like MailerSend? What's the key differentiator for early-stage companies?
Congrats on the launch! I would love a pay for what you use like Amazon SES rather than another SaaS subscription for transactional emails which spike in usage. Are there plans to add a pay per email setup rather than the monthly tiers?
Yes! Managing 'welcome emails,' 'password resets,' and 'notification digests' in our codebase has always been a clunky afterthought
Interesting launch especially when today got two email related products... Whats so special about functions related to email marketing on Sidemail? Congrats for the launch anyway!!
Congrats on the launch, i was an early customers many years ago, looks like you've come a long way. congrats.
Hi there, congratulations on your launch 🔥
Do you guys have your own infrastructure or is it AWS SES wrapper?
