Update:

Currently, using Convertkit for email newsletter with 3K subscribers

And for annoucement-
I also discovered that Gumroad offers a free newsletter service for product announcements. It can be triggered upon a purchase or used for broadcasting updates. A funny incident occurred while I was testing it – I accidentally sent a test message to all 35K users, and now I'm receiving messages from them asking what they purchased! 😛
Total opening rate in 1 hours was 20% of 31K delivered messages.

Hi,

Thank you for detailed explanation and recommendation.
* Yes, I have a weekly newsletter with 5K subscribers, and I was using Mailchimp before. Now, I want to combine my other subscribers from Gumroad (around 35K) and Lemonsquezy (3K) as well. Of course, adding all 35K subscribers at once would be too much, so I'm planning to start with around 10K subscribers for my weekly newsletter. I wanted to use Substack, but my designer instinct pushed me to create a custom email template instead of settling for Substack's standard layout. I'm looking for alternatives, and currently, I migrated around 5K subscribers to ConvertKit to give it a try.

• Yes, planning to setup other email automation as well to send to all existing gumroad member. FloDesk, I heared first time.

Let me explore this. Thanks again. Sure love to connect and discussion further.

What's your budget. I personally using
LG 27MD5KL (Best colors)
LG Ultrafine Ergo - 32Un880 (Its old though, check new version)

WH 1000x and Airpod Pro

Both looks promising. Thanks Martin. it' my weekend project to explore all these :)

Hmm, $245 seems expensive. But postmark seems great.

Thanks Rod for detailed insight. I think I have to give Amazon SES a try to configure.

Thanks Luke for suggestion. I’ll exploring this

I think I have to rethink about SES. But, PHP is not my thing here but will explore sendy. Thanks cacho

Thanks Szymon. I'll check mailerlite then :)
