Overview
Postaga
Postaga is an automated outreach platform designed to streamline your link building and digital PR efforts. Instead of manually searching for prospects, you can use the built-in CRM and discovery engine to find relevant websites, bloggers, and influencers in your niche. The software automatically finds contact information and verifies email addresses to ensure your messages actually reach the right inbox.
You can create sophisticated multi-step email sequences with merge tags that pull specific details from a prospect's website, making every cold email feel personal. It handles the heavy lifting of follow-ups and tracking, so you can focus on closing deals or securing guest post spots. Whether you are an agency managing multiple clients or a solo marketer growing a blog, the platform centralizes your entire outreach workflow in one dashboard.
Email on Acid
Email on Acid helps you eliminate the guesswork of email marketing by previewing your campaigns across over 100 different email clients and devices. You can catch rendering issues, broken links, and accessibility problems before you hit send, ensuring every subscriber has a consistent experience. The platform automates the tedious manual testing process, allowing your team to deploy high-quality emails faster and with more confidence.
Beyond simple previews, you can optimize your inbox placement with deliverability tools that check your IP against blacklists and validate your SPF and DKIM records. Whether you are a solo developer or part of a large enterprise marketing team, the platform provides the technical insights needed to bypass spam filters and improve engagement. You can integrate these checks directly into your existing workflow to maintain brand standards across every communication.
