Questions & Answers

As answered by people managing OpenCV and Mailjoy.

What makes your product unique?

Mailjoy's answer:

Compared to digital channels, mail is an unsaturated channel that until recently has been generally inaccessible and lacked personalization. Mailjoy is the tool to reach customers or prospects with mail thatโ€™s relevant and timely to them. Start by customizing any of our free postcard and letter templates.

How would you describe the primary audience of your product?

Mailjoy's answer:

We value our small, scrappy customers just as highly as our larger clients, therefore we are on a mission to bring the best tools to the masses, streamlined in a way that allows anyone to dive in and get started in minutes.

What's the story behind your product?

Mailjoy's answer:

When we launched Mailjoy on Product Hunt we received over 700 upvotes and ended up #2 for the day. We were ecstatic, but the real story here is that we actually launched nearly a month earlier without the fanfare of a traditional tech launch.

We had quietly launched Mailjoy a month earlier to a portion of our network through email outreach, Facebook, and Twitter. We had two asks: One was to share with people who might be a good fit for this. The other was to share the website more broadly on social. We ended getting over a dozen shares across different channels which drove 100โ€™s of visitors to the site.

Our first customer came from a share by a friend. By launching early, we found someone who cared enough to take a chance on us right away.

As much as we learned what converted visitors to become customers, we learned what was lacking and caused people not to convert. This helped us reprioritize our roadmap before the Product Hunt launch.

I like to consider a marketing site the showroom that entices people to take a test drive. If the showroomโ€™s offering isnโ€™t appealing, do people really want to go for a test drive? Probably not. We quickly learned what copy we were missing, as well as how potential customers viewed the product based on how we marketed it.

Our code wasnโ€™t perfect and we had bugs. Thatโ€™s OK. Visitors and users gladly pointed what wasnโ€™t working. P.S โ€” We quickly fixed things.

With a successful launch on Product Hunt behind us, we have more customers, received more feedback, and once again, are reprioritizing our short-term roadmap for things that drive the most growth and solve usability challenges. I fundamentally believe that shipping as soon as possible is the key to maximizing your learnings, and, ultimately, growing faster.

Remember, done is better than perfect.

Why should a person choose your product over its competitors?

Mailjoy's answer:

Mailjoy has a ton of features to help you create mailing lists from your contacts, design beautiful direct mail postcards and letter mailers, track the results, and integrate with other tools you already use. Sending a campaign takes only minutes. Use Mailjoy for a single campaign or make it a part of your marketing toolkit.

Additionally, Mailjoy provides recipient-level delivery tracking, conversion tracking, customer attribution, and the ability to get notified the moment a conversion happens - using unique per-mailer URLs and QR codes.

We've made sending direct mail as trackable and smart as email. Never send another direct mail campaign without the ability to track your return on investment again.
