Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Email Verification Hints Node

This node enhances email verification results by adding contextual guidance for agents (AI or human) on how to best handle email communications.

Overview

The Email Verification Hints node takes email verification results and adds an "agent_instructions" field containing predefined prompts based on the verification outcome. These prompts provide best practices for email communication, helping to improve deliverability, compliance, and user experience in automation flows.

Key Features

  • Agent Instructions: Adds predefined, contextual guidance for handling verified email addresses
  • Multiple Selection Methods: Choose instructions randomly, by fixed number, or based on email domain
  • Customizable Field Names: Configure which fields contain email and verification data
  • Invalid Email Handling: Includes custom instructions for invalid emails

Instruction Examples

  1. "Valid address. Send max 1 email every 3 days. Personalize first line; include unsubscribe footer."
  2. "Valid. Use plain-text body (<25 lines), no images, no more than 2 hyperlinks."
  3. "Valid. Subject line ≤ 55 chars, no ALL-CAPS, avoid words 'free' & 'guarantee'."
  4. "Valid. Track opens with 1 pixel; disable click-tracking to reduce spam risk."
  5. "Valid. Throttle to 200 msgs/day from this domain; pause if bounce rate > 3 %."
  6. "Valid. Add '{{first_name}},' greeting and 1 personalized company fact."
  7. "Valid. If no reply after 4 days, schedule exactly 1 follow-up; then stop."
  8. "Valid. Attachments NOT allowed; share files via link only."
  9. "Valid. Ensure SPF/DKIM pass; send from warm IP pool only."
  10. "Valid. End every email with clear postal address + easy opt-out link (CAN-SPAM)."

Usage

  1. Add the Email Verification Hints node after an email verification operation.
  2. Configure the fields containing the email address and verification results.
  3. Choose an instruction selection method (random, fixed, or domain-based).
  4. Optionally customize the invalid email instructions and output field name.

Example Workflow

  1. Verify Email → Email Verification Hints → AI Agent/LLM → Send Email
  2. The AI agent uses the provided instructions to properly format and send the email.

Use Cases

  • AI Workflows: Guide AI agents in properly handling verified email addresses
  • Automation: Ensure consistent email communication practices across workflows
  • Compliance: Maintain legal requirements for email communications
  • Deliverability: Follow best practices to improve email deliverability
