Sales outreach is a slog. If you’re calling leads all day, you know the pain of leaving the same voicemail over and over. It’s boring, it’s inefficient, and—let’s be honest—after the tenth call, you sound like a robot. Voicemail drops can help, but only if you use them right. This guide is for folks using Justcall who want to actually save time and book more meetings, not just blast generic messages into the void.
Whether you’re a solo rep or managing a team, we’ll walk through setting up, sending, and managing voicemail drops in Justcall—plus a few honest warnings about what works and what’s a waste of effort.
What Are Voicemail Drops (and When Should You Use Them)?
A voicemail drop lets you pre-record a message and “drop” it into someone’s voicemail without having to recite it every time. In Justcall, it’s a feature baked right into their calling platform.
When it’s actually useful: - Cold calling lists where most calls go to voicemail - Following up on warm leads who didn’t answer - When you want to sound polished, not rushed
When to skip it: - Super high-value prospects (they deserve a custom message) - When you need to reference something specific from the call
Pro tip: If you leave the same message for every contact, it shows. Make your voicemails sound human and mix them up as much as you can.
Step 1: Record a Voicemail Drop in Justcall
Before you can drop anything, you need a recording. Here’s how to do it without sounding like a robot.
How to Record a Voicemail in Justcall
- Log into your Justcall dashboard.
-
Use the web app; it’s easier than fiddling with your phone.
-
Navigate to the ‘Phone Numbers’ section.
-
Find it on the left sidebar. Click the number you’ll be calling from.
-
Click ‘Voicemail & Greetings.’
-
This is where you manage all your recordings.
-
Choose ‘Add New Voicemail Drop’ or ‘Upload Recording.’
-
You can either record directly in Justcall or upload an MP3/WAV file.
-
Record your message.
- Keep it under 30 seconds.
- Speak like you would to a real person, not like you’re reading a script.
- Leave your name, company, and a clear reason to call back.
Example:
“Hey, this is Alex from Widget Co. I was hoping to connect about how you’re handling team scheduling. Give me a ring at 555-123-4567. Thanks!”
- Name your voicemail drop.
-
Use a name you’ll remember, like “Cold intro – March 2024.”
-
Save it.
- Test it by playing it back. If you cringe, re-record it. No shame.
What to ignore: Don’t fuss over background music or fancy editing. People want clarity, not production value.
Step 2: Use a Voicemail Drop During Calls
Once your recording’s set, you can use it on live calls. Here’s how not to screw it up.
How to Drop a Voicemail in Justcall
- Start your outbound call as usual.
-
Dial from the Justcall dialer (web or desktop app).
-
If the call goes to voicemail, wait for the beep.
-
This is key—don’t drop your message too early, or it’ll get cut off.
-
Click ‘Voicemail Drop’ in the call controls.
-
You’ll see a list of your recorded messages. Pick the right one.
-
Hang up or move to your next call.
- The system will play your recording after you disconnect.
Pro tip: While the recording plays, you’re free to start your next call. This is how reps get through 50+ voicemails in an hour without burning out.
What doesn’t work: Don’t use voicemail drops if you need to reference something specific or if you know the lead expects a personal touch.
Step 3: Manage and Update Your Voicemail Drops
You’re not done after one recording. Managing your library keeps things fresh and relevant.
Best Practices for Managing Voicemails
- Rotate messages: Don’t use the same drop for months. Prospects talk, and recycled messages get noticed.
- Tailor by campaign: Record different drops for cold outreach, follow-ups, and event invites.
- Archive old drops: Delete or archive outdated ones so you don’t accidentally send last quarter’s offer.
- Review performance: If you use Justcall’s analytics, see which drops get the most callbacks. Double down on what works.
Real talk: No tool can make a bad script work. If your message isn’t getting callbacks, change the content—not just the delivery method.
Step 4: Stay Compliant (and Avoid Annoying People)
A feature’s only useful if you can actually use it. Voicemail drops are legal in most places, but there are lines you shouldn’t cross.
What to Know
- Check local laws: Some states and countries have restrictions on automated voicemails, especially for cold outreach. Don’t assume you’re in the clear.
- Don’t spam: If you’re dropping the same message to thousands of people, expect complaints (and probably a ban).
- Respect opt-outs: If someone asks not to be contacted, remove them. Justcall lets you manage Do Not Call lists.
What to ignore: Anyone selling “guaranteed legal compliance.” Laws change, and you’re responsible for knowing the rules in your industry.
Pro Tips for Better Sales Voicemails
You can have the fanciest tool out there, but if your message stinks, it won’t matter. Here’s what actually works:
- Sound casual, not scripted. Imagine you’re talking to a friend’s voicemail.
- Leave a reason to call back. Vague “just calling to connect” messages get deleted.
- Say your number twice. People often miss it the first time.
- Smile while you record. It genuinely makes you sound friendlier.
- Don’t apologize for calling. Own it—brief, confident, and polite wins.
What to skip: Overly formal intros (“Hello, this is Alexander Smith, Senior Account Executive at Widget Company Inc...”). You’re not leaving a message for the Queen.
Troubleshooting: When Voicemail Drops Don’t Work
Even good tools have hiccups. Here’s what to check if things go sideways:
- Drop doesn’t play: Make sure you actually waited for the beep and selected the right message.
- Audio quality sucks: Re-record in a quiet room. Don’t use tinny laptop mics if you can avoid it.
- Wrong drop sent: Double-check before you click. Delete or rename confusing files.
- No callbacks: It’s probably your script, not the tech. Test new versions.
If all else fails, Justcall’s support is usually responsive, though don’t expect miracles for stuff outside their platform.
Keep It Simple—and Iterate
Voicemail drops in Justcall are a solid time-saver if you use them right: clear message, human delivery, and regular updates. Don’t overthink it. Start with one good recording, use it, then tweak as you see what works (or doesn’t). The key is to sound like a person, not a bot—and to keep your process lean so you spend more time talking to prospects, not tinkering with tools.
Now, go record that voicemail. And if it sounds bad, hit “delete” and try again. That’s progress.
