Email Deliverability

Last Update :

Spam filtering problems are often related to the content or formatting of emails themselves. MemberLeap provides an AI Spam Analysis tool to help you check your message before sending. It is available on the Confirm Message Details screen — the final review page before sending.

The tool provides plain-language recommendations on content changes that may improve deliverability. It does not guarantee delivery, but it gives you a useful second opinion before you hit send.

Using the AI Spam Analysis Tool

On the Confirm Message Details screen, scroll down to the Spam Analysis section, located just below your list of recipients, and click Perform Spam Analysis. A window will open showing “Analyzing…” while the tool reviews your message. Results typically appear within a few seconds.

The tool reviews your subject line and the full body of your email, then suggests adjustments that may reduce the chance your message gets caught in a spam filter. It is designed to be brief and will not rewrite your message for you.

The following are deliberately excluded from analysis to protect privacy and keep feedback focused: recipient information, sender information, attachments, unsubscribe links, and the plain-text version (all added or generated automatically at send time). The tool also ignores technical noise you don’t control, such as editor-generated HTML and CSS, images hosted on trusted domains, internal system links, and email authentication settings like SPF, DKIM, and DMARC.

You can edit your message and re-run the analysis as many times as you like before sending.

Content Tips to Avoid Spam Filters

Regardless of what the tool flags, the following practices will help keep your emails out of spam folders:

Subject line:

• Avoid all caps
• Avoid excessive exclamation points (e.g., Sale!!!)
• Avoid brackets and parentheses
• Avoid referencing an attachment (commonly seen in virus emails)
• Avoid spam-trigger keywords (see below)

Body content:

• Avoid spam-trigger keywords, especially in the subject — common examples include “Sale,” “Free,” “Attention,” typical sales phrases like “buy direct,” “cheap,” or “act now,” pharmaceutical trade names, and adult-only product references
• Limit links to fewer than 5 if possible
• Avoid large images — a high image-to-text ratio can trip spam filters
• Avoid heavy use of red font coloring

If the tool flags something you intentionally included — such as a promotional word central to your message — use your judgment. These recommendations are advisory.

Sender Address

Send from your organization’s domain-based email address if one has been set up for you. Using a personal email account can cause deliverability problems because the MemberLeap mail server may not be authorized to send on that domain’s behalf. For example, if your organization’s domain is pastrychefsofamerica.org, use an @pastrychefsofamerica.org address rather than a personal one from an unrelated domain.

A Note on Spam Filters

Spam filters vary by mail server, and individual recipients can set their own rules. These tools and tips are meant to guide you as you build your message — maintaining good list hygiene and using a recognizable from-name matter too. There is no single fix that guarantees delivery, but taking these steps will
