Non-profit organizations: how to ensure email deliverability with few highlights in the year

Aug 8, 2025

An NGO doesn’t send emails every day. And that’s exactly where the challenge lies: when you rely on a few key moments to engage your audience, every email has to land successfully. To ensure good email deliverability for an NGO, it’s not enough to have a beautiful message. You also need to maintain your reputation, understand inbox rules, and keep the connection alive between campaigns. Targeting, engagement, and relevance: how can you build an effective strategy without sending emails every month?

Summary

Why sender reputation is essential for an NGO

Only sending a few campaigns a year? That could actually harm your sender reputation. For ISPs and webmails, an address that stays inactive too long and then suddenly sends a lot of emails raises red flags. Email deliverability for a Non-Governmental Organization relies on regular efforts, even outside of busy periods.

How to maintain your list between major campaigns

It’s not about overwhelming your contacts. It’s about staying present. A few light, informative, or thank-you emails can make a big difference in your NGO email strategy.

5 best practices to improve deliverability

  • Use a dedicated IP or subdomain for sending
  • Segment your lists by engagement or donation history
  • Optimize subject lines and content to avoid spam filters
  • Analyze cold metrics (open rate, clicks, unsubscribes)
  • Use a solution like Mindbaz to ensure optimized email deliverability for NGOs

How can you ensure good email deliverability when your NGO sends just a few campaigns a year?

When you send a few emails, each one matters: take care of the tech setup (SPF, DKIM, dedicated IP), nurture your list all year with useful or light content between peaks, and segment your contacts carefully to boost engagement. That’s the key to keeping a strong reputation and staying in the inbox.
