Running into this issue when setting up outgoing mail with Supabase
In your case, Supabase’s auth service is doing this:
Connects to smtp.unosend.co on whatever port you specified.
Tries to use TLS (either because you told it “SSL/TLS” in the settings or because it does STARTTLS if the server advertises it).
During the TLS handshake it checks the certificate.
The server presents a cert whose hostname is localhost.
Supabase compares that to the host you configured smtp.unosend.co and goes “nope” and throws:
I don't see a way to contact support anywhere on the site? So I am posting here to hopefully make the devs aware of this issue and resolve it?
@cyph3r
We have added Intercom Chat support For solutions.
Also we have made some changes on SMTP please refresh and try again with new flows.
If anything is missing please connect with us in chat support.
Thanks!
@bittucreator @Unosend Looking good and feature packed, pricing also makes sense. Two questions though -
1. Is there plan for drag and drop templates?
2. Why is regional pricing only for India, when there are other countries where PPP is needed even more?
@fred_ebho
Thanks for the suggestion. The new editor is coming.
Also about pricing is in india it’s bit expensive to pay $20 and we are from india so we are offering some discount to!
If you’re planning to get pro we have promo codes for others!
Feel free Drop a massage on our chat support will help you to get some discount.
Hello,
I’m having an issue when trying to send emails via the API.
This request works correctly:
curl --location 'https://www.unosend.co/api/v1/domains' \
--header 'Authorization: Bearer ***'
However, when I try to send an email with the same API key, I get an error:
curl --location 'https://www.unosend.co/api/v1/emails' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ***' \
--data-raw '{
"from": "xxx@ongtrieuhau861.dpdns.org",
"to": ["abc@example.com"],
"subject": "Test",
"html": "<p>Hi</p>"
}' => Res:
Could you please help me check why this email request is failing and let me know if there is any misconfiguration with my domain or API key?
Thank you.
@ong_tri_u_h_u We fixed
Hi, as your main purpose is to launch these email marketing tools (despite there being plenty of available ones these days), you will provide them at a minimum cost to facilitate businesses earning more of the profit while spending less on marketing. But, for now, as it's just the beginning and pricing is low, I wonder if you will follow the same pricing models in the future once it becomes as successful as others. How do you assure this cheap pricing model for the next 5 years?
I signup and add domain but email are not going to recipient

@bittucreator I will definitely give unosend a try!
My recommendation would be to change up the UI a little, it feels like a clone of resend (which I currently use) and I think that could hurt the trust of customers who already know Resend.
@soyzamudio
Thanks for the honest feedback! 🙏
We actually just redesigned our entire UI with a fresh new layout. You can check app now.
It's great to have a contender in the space to keep Resend on their toes.
I will say: I think you'd convert more people if you had the compare matrix on the homepage and not on its own page.
