Things we don’t recommend | Don'ts

Last updated: March 18, 2026

To get the best results from your AiSDR campaigns, it’s just as important to know what not to do. Below are some common mistakes users make during campaign setup — and why we recommend avoiding them.



1. Don’t enable open rate tracking, unsubscribe links, or add links in your signature by default

While these may seem like harmless additions, they can negatively impact your deliverability.

Here's why:

  • Open rate tracking inserts a hidden pixel in every email.

  • Unsubscribe links and external links in signatures are often flagged by spam filters.

  • Including these elements in every email increases the risk of your emails landing in the spam or promotions folder — especially during the early warm-up phase.

These features are not mandatory — and while they may be useful in some cases, we strongly recommend disabling them during early campaigns to protect your sender reputation and ensure higher inbox placement.

2. Don’t include links in initial outreach emails

Adding links in your first-touch email can be a red flag to spam filters, particularly when sending cold outreach.

It also shifts the focus away from your message. Early-stage emails should be short, personalized, and focused on sparking interest — not on pushing someone to click.

Instead, focus on writing clear, relevant messaging and save the links (decks, case studies, booking links, etc.) for later replies.

3. Don’t write overly long or formal emails

Long, formal emails tend to underperform for cold outreach. Here's why:

  • Most prospects skip emails — and if the core message isn’t clear in the first few seconds, it gets archived or ignored.

  • Formal intros like “Hope you're doing well” or lengthy background info dilute your core message and lose attention fast.

Instead, stick to short, sharp, and well-angled messaging. It’s more engaging, easier to personalize, and proven to convert better across industries.

4. Don’t skip LinkedIn steps — especially in tough industries

We’ve seen some customers choose not to use LinkedIn steps — but in industries like software development, IT services, and consulting, this can be a missed opportunity.

A multichannel touch (email + LinkedIn) is much more effective at getting attention. If a prospect misses your email, a well-placed LinkedIn touchpoint can act as a second chance to engage them.

Especially in competitive markets, hitting your leads from multiple angles often makes the difference between silence and a booked meeting.

5. Don’t create a campaign with leads from multiple time zones

AiSDR campaigns are designed to send emails within local business hours — a key factor in visibility and reply rates.

However, you can only assign one time zone per campaign. If you mix leads from all over the world in one campaign, some of them will inevitably get emails at odd hours — reducing performance and hurting deliverability.

Instead, we recommend creating separate campaigns per region or time zone, so each lead receives your message at the optimal time.

6. Avoid mixing completely different industries or roles in one campaign

Combining multiple, unrelated industries in a single campaign makes it difficult to write messaging that resonates. Each industry has its own language, pain points, and context — and trying to speak to all of them at once usually results in generic, low-performing outreach.

The same applies to mixing different seniority levels (e.g. C-suite + mid-level managers). Messaging that works for a VP likely won’t land the same way with a specialist or coordinator.

Instead, keep your campaigns focused on one industry (or closely related ones), and target roles within a similar management level. This helps align your messaging more precisely — and gets better results.

7. Avoid running bulk searches when testing filters or exploring search criteria

If you're unsure whether a set of filters or criteria will return the right leads, don’t run a full bulk search right away.

Instead of pulling 500+ leads upfront, start with a small batch of 10 to evaluate relevance. Once you confirm the quality, you can scale the search confidently.

This is especially important when using CSV company imports. If you're uploading a list of companies, reduce the "leads per company" setting to around 10 leads per company initially. This prevents performance issues and helps you validate lead relevance before scaling up to larger batches.

Keep in mind: your subscription includes one search credit per message credit — so if you have a 1,000-message plan, you get 1,000 search credits. Avoid wasting credits on test searches that might not be usable.

Testing smart saves time and credits.

8. Don't overfill the lead search filters — more isn’t always better

When searching for leads in the Lead section, it can be tempting to fill in all the available fields: job title, management level, department, and keywords. But in reality, adding too many filters often limits the search too much — and you risk excluding highly relevant leads.

What we recommend instead:

Use only one of these combinations:

  • Just the job title

  • Management level + department

  • Keywords in titles + management level

This gives the AI more flexibility to return a broader pool of qualified and relevant leads, while still staying focused on your ideal ICP.
