How to Multiply Your Leads with Bulk Email Marketing

The article ‘How to Multiply Your Leads with Bulk Email Marketing’ was originally Published in March, 2019. It has been reworked and modernized for 2021. 


If you’re looking for a way to quickly scale up your lead generation, bulk email marketing is one of the best opportunities out there. It has vast potential and can bring in the marketing-qualified leads (MQLs) much faster than any other kind of content.


The key factor in being successful is preparing and knowing what to do before you get started.


We’re going to examine the potential of bulk email marketing and why it’s such a powerful method.


How to Multiply Your Leads with Bulk Email Marketing


It’s important to differentiate between opt-in and cold email marketing, and set your expectations accordingly. The approach we’re talking about is targeted at cold contacts – that is, people who’ve never heard of you.


Let’s consider open rate. For an opted-in list, depending on your industry, you can expect an open rate between 20% and 40%. Which makes sense, since the people receiving your email are people who have signed up and stated “I want to receive emails from you”.


Cold email requires a whole other mindset, though. The people receiving your email aren’t expecting it, and so you can’t anticipate the same open rates as with an opted-in list. For cold email, 3-5% open rate is considered excellent.


People tend to see this kind of open rate and decide that cold email isn’t for them. However, what bulk email marketing lacks in high open rates, it more than makes up for in reach.


How Is Bulk Email Better?

If we’re talking about a tenth of the open rate, then you’ll get a tenth of the leads, right? Well, no – it’s a matter of scale. The clue is in the name – you send emails in bulk, meaning your recipient list is going to be much larger than with your opt-in list.


Let’s run a quick comparison of the two. We’ll say the open rates are average: 25% for opt-in, 2.5% for cold. The maximum number of emails you can send daily from most opt-in email providers is 1000, so we’ll use that. Our list size for bulk email will be 100,000 – though you could easily send to double, triple or even ten times that many contacts if you desired.

Opt-In Cold


1000 100000
Open Rate 25%


Opens 250



As you can see, even with one-tenth the open rate, bulk email generates ten times the number of opens that opt-in does. And the larger your recipient list is, the more that gap widens.


As with an opted-in list, it’s important not to over-send to your cold contacts. Space out your email sends widely to avoid audience fatigue and a spike in unsubscribe rates.


Eventually, after testing and experimentation, you should be able to send using a cadence that directly appeals to your audience.



What About Nurturing?

Nurturing your email leads is crucial to guiding them to a purchase. If you just blast a bottom-of-funnel message at 100,000 cold contacts trying to get them to buy your product, you’ll most likely see a huge unsubscribe rate and risk getting blacklisted for spamming – not to mention, you still won’t get the purchases you’re looking for.


Don’t try to force leads down the funnel. In fact, don’t think of your bulk email marketing as a separate entity at all. Instead, think of it as widening the top of your existing funnel. Use your bulk email to drive opt-ins and then add them to your nurturing cadences.


Once they’re well-nurtured and warmed up, then you go for the sale. If you need tips on crafting strategy and content for your emails, check out our guide to cold email copywriting.


Where Do I Get Such a Big List?

Opt-in lists are earned by constantly outputting a stream of valuable content, attending events, advertising on social media, performing SEO, and so on. All that effort yields warm, engaged leads – but at a trickle. Building a list of 100,000 subscribers would take a ridiculous amount of time.


So where do you get such an immense list?


There are numerous ways, and almost all of them are terrible ideas that do your marketing more harm than good. Take scraping, for example: there are tools out there that will crawl the internet for you and retrieve (or scrape) email addresses they find.


These bots can be highly sophisticated, able to puzzle out even email addresses that aren’t actually formatted as email addresses. For example, if you wrote out “my_email (at) provider (dot) com”, a scraper bot could still get your email from that string of text. They can generate email lists quickly, but they come with two deal-breaking problems.


The first issue is that you have no way of knowing who’s behind the email addresses. You can’t possibly know if what you’re sending is in any way relevant to them, so emailing them absolutely constitutes spam. Spamming gets you blacklisted and destroys your sender reputation, which effectively puts an end to your email marketing in general. In short, you don’t want to do it.


Don’t Just Scrape By

The second issue is that the quality of the list that these bots generate is awful. Their sophistication works against them in that regard – let’s say they find a post somewhere that says “Everyone is at the library. Join us upstairs!”. A scraper bot would interpret that as “everyoneis@thelibrary.join”, which is obviously not actually a real email address.


Even when the email addresses it finds are real, there’s still a risk of the email being a spam trap. These are addresses that exist solely to flag spam. They may have once been actively-used addresses that have since been repurposed, or they may have been created expressly to track spam. Either way, sending to one of these can result in you being blacklisted as a spammer.


Don’t use scrapers (or scraped email lists).


The best, most reliable and safe way to acquire a large cold email list is to use a reputable data provider. You can purchase a list that’s tailored to your needs and targeted at the right audience, and be confident in the quality of the data you’re using.
