With a $150 budget, should I use Facebook ads or cold email marketing to sell my services?
Definitely go with cold email marketing. With $150 you can run a cold‑email campaign for about 2–3 months (roughly 60–75 days) sending around 300 emails per day, which gives you many shots at landing a paying client. Facebook ads at that budget are ineffective—you’d need roughly 10× the spend just to begin to understand whether the campaign is working, making it a poor choice for lead generation when funds are limited.
I bootstrap the vast majority of my business using cold email, which is why I encourage everyone I know to use it. The cost per acquisition (CPA) with cold email is significantly lower than with paid ads—in 99% of cases it's not even funny how much lower it is. With cold email, you trade the inherent scalability and automation of ad platforms (like Google and Facebook's automated tweaking and tripwire offers) for the time you or a salesperson spend communicating one‑on‑one with prospects. Because you're investing that time, the CPA drops dramatically—for example, you might spend around $5 to acquire a $5,000 product, whereas with ads you could spend $350 or more for the same lifetime value. Even with a $100‑per‑month budget, you can't realistically run an ad campaign; the time, energy, and money required to set up and optimize the ads would be prohibitive. Cold email lets you use that budget effectively by focusing on direct outreach.
No, for the same reasons I've mentioned before — ads don't really make sense at small budgets. It typically takes something like 10x that budget just to begin to tell whether a campaign is actually working or total garbage.
Use a done-for-you mailbox provider; I recommend Zapmail (with affiliate code Nyx for 10% off). Get 9-12 mailboxes at about $3.50 each per month; with the discount that's roughly $33 total. Buy domains—one domain per three mailboxes—so about 3-4 domains at ~$10 each, adding ~$35. Set up Instantly: the $37 plan works if you're bottlenecked, bringing the total to about $105, leaving $15 for Make.com (or n8n) for personalization. You can also scrape leads for free using Apollo or Apify, then personalize them for a few dollars per thousand. Overall you can start with around $70.
Cold email is generally better than ads for service businesses aiming to book meetings. With the same approach, a meeting might cost around $10, and if one in three meetings becomes a client, the customer acquisition cost is about $30 on a $5,000 deal—roughly 6% of the margin spent on acquisition. Ads on a B2B offer might be 2‑3× more expensive. The cold‑email advantage has decreased as the space saturates, but it’s still two to three times better than ads for many offers, so it’s worth starting now while the opportunity lasts.
