How to run multichannel outreach campaigns with Maildoso step by step

Cutting through the noise isn’t easy. If you’re trying to get real replies from prospects—whether you’re in sales, recruiting, or partnerships—you already know that sending one email blast won’t cut it. Multichannel outreach is the way to go, but juggling email, LinkedIn, and other channels can get messy, fast.

This guide is for anyone who wants to actually run a multichannel campaign, not just read about it. We’ll walk through setting up, launching, and managing a campaign using Maildoso. No fluff, no “growth hacking” nonsense—just what works, what doesn’t, and how to avoid spinning your wheels.


Step 1: Get Your Basics in Place

Before you even open Maildoso, get your ducks in a row:

  • Define your goal. Are you booking calls? Trying to hire? Selling something? Be clear, because this shapes everything else.
  • Know your audience. Vague lists are useless. Build a list with real names, accurate emails, and (if you’re using LinkedIn) up-to-date profiles.
  • Decide your channels. Multichannel doesn’t mean “use everything.” Usually, it’s email + LinkedIn. Don’t add more unless you have a real reason.

Pro tip: Don’t waste time on “spray and pray” lists. Quality trumps quantity every single time.


Step 2: Set Up Maildoso the Right Way

Assuming you’ve signed up for Maildoso, let’s get it ready. This isn’t rocket science, but skipping steps here will come back to bite you.

Connect Your Accounts

  • Email: Link your sending account (Gmail, Outlook, whatever you use). Authenticate properly—don’t skip SPF/DKIM setup or your messages might land in spam.
  • LinkedIn: Maildoso lets you hook up your LinkedIn for automated messaging and connection requests. Be ready to log in and approve permissions.
  • Other channels: Only add these if you actually plan to use them.

Watch out: Don’t connect personal accounts you can’t afford to have limited or banned. Outreach tools sometimes trigger platform flags, especially on LinkedIn.

Warm Up New Accounts

If you’re using a brand-new email or LinkedIn account, warm it up first. That means:

  • Send a handful of real, human messages per day for a couple weeks.
  • Don’t blast 100 strangers out of the gate.

Maildoso has some warm-up features, but don’t expect miracles. No tool can “trick” Google or LinkedIn for long.


Step 3: Build Your Target List

This is where most campaigns go wrong. Bad data = angry prospects or no replies.

Import or Create Your List

  • Import CSV: Most people start here. Clean your file: no weird characters, missing emails, or duplicate rows.
  • Enrich data: If possible, add first names, company names, and LinkedIn URLs. More fields = more personalization.

Segment Your List (Optional, but Smart)

  • Break your list into logical groups (by industry, job title, whatever matters).
  • Run separate campaigns for each group so your messaging makes sense.

What to ignore: Don’t obsess over dozens of micro-segments if you’re just starting out. Two or three clear groups are plenty.


Step 4: Write Messages That Don’t Suck

Templates are everywhere, but most sound like robots wrote them. Here’s how to avoid that:

Craft Your Sequences

  • Email: Start human. Short, direct, and no jargon. Personalize with first names and, if you can, something specific about them or their company.
  • LinkedIn: Keep it even shorter. If you’re sending a connection request, don’t pitch—just say why you want to connect.

Build Multichannel Steps

A good sequence might look like:

  1. Email #1: Quick intro, clear reason for reaching out.
  2. Wait 2-3 days.
  3. LinkedIn connect request (no pitch).
  4. Wait 2 days.
  5. LinkedIn message if connected.
  6. Email #2: Light follow-up, maybe a new angle.
  7. End.

You can do more, but don’t overdo it. Five to six total touches is fine.

What works: - Personalization (use their name, company, or something recent they did). - Clear, specific asks (“Are you the right person for X?” is better than “Let’s connect.”) - Simple language.

What doesn’t: - “Hope you’re well in these uncertain times…” Just don’t. - Huge paragraphs. - Sending messages every day. Give people space.


Step 5: Set Up Your Campaign in Maildoso

Now, finally, back to the tool.

Create a New Campaign

  • Pick the right channel order (usually email first, then LinkedIn).
  • Upload your cleaned contact list.
  • Set sending limits (Maildoso lets you throttle sends so you don’t get flagged as spam).

Add Your Message Steps

  • Plug in your email and LinkedIn message templates.
  • Use Maildoso’s personalization fields, but review them—sometimes the variables don’t work as expected.
  • Set delays between steps. Don’t do “same day” follow-ups.

Test Everything

  • Send test messages to yourself or a colleague.
  • Check for broken links, weird formatting, or missing personalization.

Pro tip: Maildoso’s preview feature is good, but nothing beats sending a real test to a live inbox.


Step 6: Launch—and Monitor Closely

Hit “start,” but don’t walk away.

Watch Deliverability

  • Check for bounce rates. If more than 5% of your emails bounce, your list is bad or outdated.
  • Monitor spam complaints. If you see these, stop the campaign and fix your copy or list.

Reply Handling

  • Maildoso can auto-stop sequences when someone replies, but check this yourself for the first few runs. You don’t want to send a follow-up to someone who already answered.

LinkedIn Rate Limits

  • Don’t max out the number of connection requests/messages per day. LinkedIn is cracking down hard.

Adjust as You Go

  • If a step is bombing (no replies, lots of unsubscribes), pause and tweak it.
  • Remove contacts that bounce or ask to be removed.

What to ignore: Don’t obsess over “open rates.” Focus on replies and conversations started. That’s what matters.


Step 7: Track Results and Iterate

Maildoso gives you stats, but don’t drown in them.

Focus on These Metrics:

  • Reply rate: Did anyone actually talk to you?
  • Positive responses: Not all replies are equal. Track the ones that move you forward.
  • Connection rates: For LinkedIn, how many accepted your request?

Make Small Changes

  • If one message is working, double down on it.
  • If something flops, change only one thing at a time. Subject line, message length, or timing.

Pro tip: Don’t rewrite your whole sequence after a week. Campaigns take time to get real data.


Real Talk: What Works, What Doesn’t

  • Works: Short, honest messages. Lists with recent, accurate data. Mixing channels, but not spamming.
  • Doesn’t: Over-automation. “Personalized” messages that aren’t actually personal. Ignoring replies.

Ignore the hype: No tool can replace doing the basics well. Maildoso is helpful, but it’s not magic. If your list or message is bad, nothing will save you.


Keep It Simple—And Iterate

Multichannel outreach isn’t about complexity—it’s about persistence and relevance. Don’t overthink it. Start small, pay attention to how people respond, and tweak as you go. With some focus, Maildoso can help you reach more people (without annoying everyone in the process). Keep it human, keep it simple, and you’ll see results.
