I rebuilt my outreach this week after my reply rate tanked from 4% to <1%. Pulled fresh data from 5+ deliverability blogs (Autobound, MarketingProfs, HyperGen, Instantly), built a Python validator to enforce the new rules across 70+ template files in my repo, and shipped 10 trimmed emails that comply. - Source: dev.to / 2 months ago
Instantly was my final selection given its API was the most robust and well documented. It gave claude full access to campaigns, leads, and sequences while also being capable of sending webhooks on reply and unsubscribe events. - Source: dev.to / 6 months ago
Anywho, the old mailgun system was able to send emails immediately + had images in them. The recommendations we got were to remove ALL images, and instantly.ai has to delay a few minutes between email. So the emails get out slower and no images, plain text looks a lot more scammy to me and I assume also hurts conversions? Source: almost 3 years ago
What about instantly.ai? Any experience around that? Source: about 3 years ago
Yeah, well that's just how it works. You'll need to warm up your domain, there's a lot of ways to do it I would suggest something on the lines of https://instantly.ai/. Source: about 3 years ago
GStack is Garry Tan's Claude Code setup, and at nearly 110,000 stars it is one of the most popular skill collections out there. Instead of one mode that handles everything, it gives the agent distinct roles, each behind its own slash command. It has product vision, designer, engineering manager, release manager, doc engineer, QA, and post-launch retrospective. It is the same genre as Superpowers, a full workflow,... - Source: dev.to / 23 days ago
That is the design. And it is why GStack โ Garry Tan's open-source Claude Code skill setup โ has accumulated 82,700 stars and 12,000 forks on GitHub since its March 2026 launch. - Source: dev.to / 2 months ago
This is not the first time. Tan's previous project, gstack, has amassed over 69,000 GitHub stars. Developer Mo Bitar described it as "a bunch of prompts in a folder." Another founder noted that without the YC title, it would not have made Product Hunt. A developer who examined Tan's AI-generated website code found 78,400 lines including empty CSS files, duplicate assets, and test files shipped to production. - Source: dev.to / 3 months ago
And I believe any builder should use Gstack from Garry Tan. Old news I know, but for people who live under a rock like I do. - Source: dev.to / 3 months ago
