What Makes a Great Cold Email? Lessons from Testing SendRizz

Cold email isn’t dead—it’s just usually done wrong.

At SendRizz, we’ve tested our own product the way we expect our users will: real outreach, to real prospects, from real Gmail accounts. Along the way, we’ve seen what works, what gets ignored, and what gets flagged.

Here are five hard-earned lessons from using SendRizz internally to power cold outreach—and how the product is designed to support each one.


1. Get to the Point in 3 Sentences or Less

Your recipient is busy. The worst thing you can do is bury your ask in a wall of text.

What works:

  • A short intro that proves you’re relevant
  • A crisp value proposition
  • A clear call to action (CTA)

Example:

Hi [Name],
I saw you’re hiring SDRs—thought this might help.
We built a tool that lets reps send Gmail-based campaigns with open tracking and scheduling, without touching code. Want a quick demo?

How SendRizz helps:
Our built-in editor forces simplicity. No HTML templates. No flashy designs. Just plain-text or clean formatting that reads like a normal email—because it is one.


2. Personalization Beats Persuasion

You don’t need to convince someone you’re brilliant. You need to show you’ve done your homework.

What works:

  • Referencing something recent (a hire, product launch, blog post)
  • Connecting over a shared problem
  • Keeping it one-to-one

How SendRizz helps:
SendRizz supports contact-level personalization fields (like {name}, {company}, {job_title}) and includes preview-as-you-write so you can quickly sanity check your campaign.

Soon, we’re adding basic AI assist to generate personalized intros based on imported CSVs.


3. Timing and Consistency Matter

Cold emails rarely land a response on the first try. That’s why scheduling and follow-up logic are key.

What works:

  • Sending at the right hour (usually mornings, mid-week)
  • Following up 2–3 times with context
  • Respecting the line between persistence and spam

How SendRizz helps:
You can queue emails with scheduled delivery windows, and we track daily Gmail limits so your sending remains safe and spread out. A lightweight follow-up sequence feature is in the works.


4. Track, But Don’t Obsess

Open tracking is useful. But chasing opens alone won’t make your campaign successful. What matters is engagement—and ultimately, replies.

What works:

  • Using opens to inform timing and follow-up
  • Measuring reply rates as the true north
  • Avoiding gimmicky tricks (like fake FWD: or RE:)

How SendRizz helps:
Each campaign includes lightweight open tracking using a simple pixel. You’ll see who opened, when, and how often—but we intentionally don’t gamify it. The goal is focus, not vanity metrics.


5. Make It Easy to Say Yes

The best cold emails aren’t about selling—they’re about starting a conversation.

What works:

  • A soft ask (e.g., “Interested in learning more?” or “Worth a quick chat?”)
  • A link to book a time (Calendly or similar)
  • Zero friction

How SendRizz helps:
Because it sends from your actual Gmail account, replies go directly to your inbox—no forwarding, no message center. It’s you, continuing the conversation.


Final Thought

Great cold emails don’t rely on hacks. They rely on empathy, clarity, and timing.

SendRizz doesn’t try to do everything. It just helps you send smarter cold emails—straight from Gmail—with the tools you actually need:

  • A clean editor
  • Personalization
  • Scheduling
  • Open tracking
  • Safe sending limits

That’s it. No noise. No templates. Just a better way to start conversations that matter.
