If you're running B2B outreach, you know the drill: cold emails still work, but only if they're not… well, cold. Personalization is the difference between a reply and a one-way ticket to the spam folder. If you're not a natural copywriter—or just tired of rewriting the same intro 50 times—AI tools like Writesonic promise to save you hours. But can it actually help you send emails that people want to read, or is it just another way to churn out generic fluff?
This guide is for founders, sales reps, marketers—anyone who needs to write emails that sound like a human, not a robot. I’ll walk you through how to use Writesonic to build personalized cold email sequences that don’t suck. No hype, just what actually works.
Step 1: Get Clear on Who You’re Targeting (Don’t Skip This)
Before you even open Writesonic, know exactly who you’re emailing and why. AI can’t fix a vague value proposition or a spray-and-pray contact list. Here’s what you need ready:
- A defined list of leads: Names, companies, email addresses. Ideally, some context—like recent funding, a new role, or public news.
- Your offer: What problem do you solve? Why should this person care?
- Personalization data: Anything specific you can mention. LinkedIn activity, recent press, product launches, etc.
Pro tip: If your list is just “anyone with a pulse at a SaaS company,” back up. The more specific your inputs, the better your results.
Step 2: Set Up Writesonic and Choose the Right Tool
Once you’ve got your list and angle, log into Writesonic. There are a bunch of templates for email, but for B2B cold outreach, you’ll want the “Cold Email” or “Email Sequence” tool.
- Cold Email: Good for one-off intros or follow-ups.
- Email Sequence: Best if you want 3–5 emails that build on each other—initial outreach, gentle nudge, breakup email, etc.
Pick the tool that matches your workflow. Don’t get lured in by “all-in-one” templates unless you want cookie-cutter results.
Step 3: Feed Writesonic the Right Inputs
This is where most people get lazy. Don’t just paste your generic company pitch and hit “generate.” The AI is only as good as what you put in.
Here’s what you should prep:
- Recipient’s info: Name, company, role, and any trigger event (promotion, hiring, etc.).
- Your value prop: One sentence on what you do, and why it matters to them specifically.
- Tone and style: Most B2B emails are too stiff. Set the tone you actually want: casual, direct, friendly, etc.
- Call to action: Be clear. “Can we book a quick call?” is better than “Let me know if you’re interested.”
Example input: - Recipient: Jane Doe, Head of Operations at Acme Corp - Trigger: Just raised Series B - Value prop: “We help growing ops teams automate onboarding—saving 10+ hours a week.” - Tone: Direct, conversational - CTA: “Worth a quick 15-minute call?”
Pro tip: If the tool lets you add “personalization snippets,” use them. That’s where you mention specifics (“Saw your post about remote onboarding—great insights!”).
Step 4: Generate, Tweak, and Don’t Settle for the First Draft
Hit “generate” and you’ll get a handful of emails. Some will be… bad. That’s normal. AI is fast, but not magic.
What to look for:
- Clarity: Does the email actually make sense to a human?
- Specificity: Does it mention something real about the recipient, or just generic flattery?
- Length: Shorter is almost always better.
- Hype: Watch for fake urgency (“Act now!”) or over-promises. These kill trust.
Edit ruthlessly. Combine the best bits from different drafts if you need to. Don’t be afraid to rewrite the subject line—AI tends to play it safe (“Quick question,” “Introduction from [Your Company]”). Those are boring.
What not to do: Don’t send the first AI draft without reading it. That’s how you end up on r/ChoosingBeggars.
Step 5: Sequence Your Emails (If You’re Sending More Than One)
If you’re running a sequence, map out what each email does:
- First email: Short intro, personalized hook, clear ask.
- Follow-up 1 (2–3 days later): Reference the first email, add a new angle or social proof.
- Follow-up 2: Even shorter. Maybe a “just bumping this up” with a relevant case study.
- Breakup email: Polite, gives them an out (“If now’s not the right time, no worries.”)
Writesonic can generate sequences, but you’ll need to check for repetition. AI loves to rephrase the same thing three times. Make sure each email actually adds something new.
What works: - Polite persistence (2–3 follow-ups max) - Adding new value (case study, resource, relevant news) - Always making it easy to say no
What doesn’t: - Guilt trips (“I noticed you haven’t replied…”) - Vague asks (“Let’s connect sometime”) - Overly aggressive CTAs
Step 6: Personalize at Scale—But Don’t Fake It
Here’s the deal: “Personalization” isn’t just dropping in a first name. If the rest of your email screams “template,” you’re still invisible. Writesonic lets you add personalization fields, but you’ve got to supply the data.
What actually works: - Mentioning something recent (a blog post, press, funding, hiring) - Noticing a specific pain point (from LinkedIn, company news, etc.) - Keeping it honest—don’t pretend to know them if you don’t
What doesn’t: - “I came across your impressive profile…” (Everyone gets these. Nobody cares.) - Flattery for its own sake - Overpromising (“I guarantee we’ll 10x your ROI!”)
Pro tip: Build a spreadsheet with columns for each personalization snippet. Merge these into your Writesonic inputs, either manually or with their API/integrations (if you’re getting fancy).
Step 7: Test, Send, and Track—But Don’t Obsess
Once you’ve got your sequence, send a few test emails to yourself or a colleague. Check for:
- Formatting issues (bad spacing, weird fonts)
- Placeholder fails (did {{first_name}} get replaced everywhere?)
- Broken links or typos
Send small batches first. See what gets replies, what gets ignored, and tweak from there. No tool (AI or not) can predict exactly what’ll work for your audience.
What matters: - Open rates (subject line + sender name) - Reply rates (body + CTA) - Actual conversations (not just “interested” clicks)
Don’t get hung up on vanity metrics. If nobody replies, your email sucks—start over.
Honest Pros and Cons of Using Writesonic for Cold Email
What Works
- Speed: You can create dozens of drafts in minutes, not hours.
- Structure: Good for beating writer’s block—never staring at a blank screen.
- Decent personalization placeholders: Especially if you prep your data.
What Doesn’t
- Quality varies: The best emails still need heavy editing.
- Generic by default: If your inputs are lazy, your emails will be too.
- Repetition: AI-generated sequences often repeat themselves or sound robotic if you don’t tweak.
What to Ignore
- “AI will replace your SDR team!” No, it won’t. Use it as a tool, not a crutch.
- Pre-made templates for “any industry.” The more generic, the less effective.
- Any promise of “guaranteed replies.” Cold outreach is always a numbers—and quality—game.
Keep It Simple and Iterate
Personalized cold emails aren’t about tricking someone into replying. They’re about showing you did your homework and respecting their time. Writesonic is a solid tool for getting started faster, but your results will always come down to the effort you put in up front.
Start small, keep your outreach tight, and don’t overthink it. Iterate, learn, and remember: nobody wants another email from a robot. Make it real, and you’ll stand out.
