When you send a proposal, contract, or update through Releventful, you want your clients to see it — not find it in their spam folder later.

Email providers like Google (Gmail), Microsoft (Outlook), and Apple (iCloud) each use their own algorithms to decide which messages are trustworthy and which look suspicious. While Releventful already takes care of all the behind-the-scenes technical work to make your emails deliver reliably, those systems also look closely at what your message says and how it’s written.

Here are a few simple ways to make sure your emails consistently land in your clients’ inboxes.

Emails that sound like a real person wrote them almost always perform better. Filters look for overly formal or robotic language — so write like you’re talking to your client.

Good examples:

“Hi Sarah, here’s your updated proposal for the Smith wedding.”
“Hi Mark, I’ve attached your contract — please let me know if you have any questions.”

Avoid:

“IMPORTANT: VIEW YOUR PROPOSAL NOW”
“Click here for your document.”

Friendly, natural communication builds trust and helps your messages get through.

Your subject line should clearly describe what’s inside.
​

Avoid hype or overly “salesy” language — email systems see that as a warning sign.

✅ Best: “Updated Event Proposal for May 10”
​⚠️ Avoid: “Act Now!” or “Important Information – Open Immediately!”

If you keep it simple and genuine, your message will look credible to both clients and filters.

Emails with mostly images and very little text can appear suspicious to spam filters.
To help your messages pass cleanly:

Releventful’s built-in templates are already optimized for clarity and deliverability — just add your own friendly message to personalize it.

Releventful automatically includes only one secure, branded button in your emails — for example, to view a proposal or sign a contract. That’s exactly what inbox filters expect from a legitimate, one-to-one business message.

If you add custom text or links, keep them minimal and relevant. Avoid:

When in doubt, keep it simple — one clear action is best.

Even a perfectly legitimate email can trigger filters if it uses certain styles or phrases. Avoid:

Stick with a calm, professional tone that matches your brand voice.

A clear signature helps clients (and their inbox providers) recognize your business instantly.

You can set this up in Releventful → Settings → Communication Pref -> Email Signature.

Add your name, business name, website, and phone number — these details automatically appear at the bottom of your outgoing messages.

Example:

Thanks,
Olivia
Maplewood Events

A consistent signature reinforces professionalism and brand trust.

When your clients open, reply to, or interact with your emails, it teaches their email provider that your messages are safe and wanted.

Encourage them to:

Engagement is one of the strongest positive signals for inbox placement.

If you’re following up with multiple clients, try not to send all your messages at once.
Regular, consistent communication looks more natural to email systems — and helps maintain a strong sending reputation over time.

Before you hit “Send,” take a moment to review:

Sending a quick test email to yourself is always a good idea to see how it looks from your client’s perspective.

Releventful automatically takes care of the complex parts of email delivery — from authentication to sender identity and safe links — so your messages start from a position of trust.

By keeping your content personal, clear, and professional, adding your business signature, and encouraging client engagement, you’ll ensure every proposal, contract, and update reaches your clients’ inbox exactly as intended.
