The scale problem isn't obvious at first
At 3–5 accounts, manual launching is tolerable. At 50+, the same action (create a campaign, ad set, ad, set a budget) has to be repeated dozens of times for the same offer, differing only by account. That's not just slow — it's a source of errors: somewhere you forgot to switch the budget currency, somewhere you pasted the wrong pixel.
A preset is a template, not browser automation
The approach that actually scales isn't "click faster" — it's not clicking at all: build the campaign structure (campaigns/ad sets/ads, budget, copy, creatives, targeting) once as a preset, then just check accounts and launch. One preset expands into as many campaigns as accounts selected, with a log per account.
Request pace is part of scale too
Launching on 50 accounts at once is a sharp burst of identical requests to the Meta API. The official API allows this technically, but a rapid series of identical edits across dozens of objects raises the odds of hitting a Facebook risk review (covered in "Why Facebook Bans Ad Accounts"). A tool that launches through the API at a sensible pace, rather than one simultaneous burst, lowers that signal structurally — not through a trick.
What to check before launching on 50+ accounts
- Every account has a Page ID set — without it, Facebook simply won't let you launch on that specific account, and it's better to find that out before, not after, clicking "Launch".
- Budget currency in the preset — with accounts in different currencies, the budget should convert at the launch-date rate, not stay in one currency for all.
- A/B copy variants — if testing multiple ad variants, use explicit variants (AdFleet allows up to 5 per field — AdFleet's own limit, not a Meta rule), not random generation for "uniqueness".
If something fails midway
At 50+ accounts, a failure on at least one is nearly guaranteed, not an exception (network blip, an API limit, a transient Facebook error). A tool with no step-by-step log in a database re-creates campaigns from scratch on retry — duplicates on every account that already succeeded. The right architecture logs every step to a database (not process memory) and, on retry, resumes from where it stopped, not from the start.
