You’ve written the perfect email. It’s personalized, well-timed, and packed with value. You hit “send”… and then? Crickets. No opens. No replies.
The culprit? It might not be your content — it might be your email deliverability.
If your emails aren’t making it to the inbox, all your effort goes to waste. The good news is, improving deliverability doesn’t have to be technical or confusing — especially when you’re using the right automation tools like PostSheet.
In this post, we’ll walk you through what email deliverability is, why it matters, and how to boost it using automated (but still human-feeling) emails.
What Is Email Deliverability, Really?
Deliverability is your email’s ability to actually land in someone’s inbox—not the spam folder, and definitely not the promotions tab.
It’s affected by a mix of factors, including:
- Who you’re sending from (your domain & email account)
- How your emails are written (spammy language = 👎)
- Sending volume and frequency
- Engagement rates (opens, clicks, replies)
- Whether your emails look “real” or automated
Even if you’re doing everything right with your content, bad deliverability can silently kill your results.
Why Automated Emails Can Help (Or Hurt)
Most mass email tools send from third-party servers — which can trigger spam filters. But PostSheet sends emails directly from your actual email account (like Gmail or Outlook), which helps your messages look more like natural, 1:1 communication.
Done right, automation can actually improve your deliverability. Here’s how.
5 Ways to Boost Deliverability with Automated Tools Like PostSheet
1. Send From a Real Email Address (Not a Noreply@)
Spam filters hate generic “noreply” addresses. Instead, send from a personal account that includes your name. For example:
✅ julia@yourcompany.com
❌ noreply@yourtool.io
With PostSheet, you connect your real email account—so messages feel legit from the start.
2. Use Personalization Tags (They’re Not Just for Looks)
Emails with dynamic fields like {{First Name}} or {{Company}} don’t just feel more human — they also reduce your chance of hitting the spam folder.
Why? Because unique content per recipient = lower spam score.
Even small personalization like the recipient’s name in the subject line can boost open rates and signal to filters that your emails are real.
3. Avoid Spam Trigger Words
Some phrases can immediately tank your deliverability. Steer clear of:
- “Act now!”
- “Risk-free”
- “Congratulations!!!”
- “Get rich quick”
Instead, keep things conversational and simple. PostSheet doesn’t just automate your emails — it encourages plain, human language that inboxes prefer.
4. Send in Smaller Batches (Especially if You’re Just Starting Out)
Suddenly blasting 1,000 emails from a new domain? That’s a red flag.
PostSheet lets you control your send volume and schedule emails over time, helping you “warm up” your domain and avoid getting flagged as a spammer.
Pro tip: Start with smaller lists (~50–100 per day) and ramp up gradually.
5. Make It Easy to Reply
When people reply to your emails, it’s a strong sign to inbox providers that you’re legit.
So don’t send emails that feel robotic or salesy. Ask a question. Invite a conversation.
PostSheet lets you send personalized outreach that’s meant to be answered — not ignored. More replies = better deliverability over time.
Bonus Tips for Technical Clean-Up (If You’re Ready for It)
- Set up SPF, DKIM, and DMARC records: These authenticate your domain. If you’re unsure how, ask your domain host or IT person.
- Use a custom tracking domain: If you’re including links, this can help build trust.
- Clean your list regularly: Remove bounced emails and unresponsive contacts.
PostSheet doesn’t require these technical steps to get started, but doing them can help if you’re sending a high volume of messages regularly.
How PostSheet Helps You Stay in the Inbox
Here’s how PostSheet is built with deliverability in mind:
✅ Sends from your own email address (not a shared server)
✅ Makes personalization easy and natural
✅ Lets you preview every email before it goes out
✅ Gives you control over sending speed and timing
✅ Keeps your outreach feeling like real human communication
In short, it combines the power of automation with the authenticity of real email.
Final Thoughts: Deliverability = Visibility
It doesn’t matter how good your offer or message is if it never lands in the inbox.
By using tools like PostSheet and following a few best practices, you can send smarter, more effective emails — and get the opens, replies, and results you deserve.
