The single biggest time sink in running a Fansly creator agency is manual mass messaging — chatters copying templates, scheduling DMs, segmenting fans, and clicking send across dozens of creator accounts. The Fansly Mass Messaging API turns that into one workflow per creator that runs in minutes, hits every fan with personalized content, and tracks who converted.
This guide covers what the API does, how to set up a mass message campaign, the use cases that pay back fastest, and the credit budgeting agencies should think about before scaling.
What Fansly mass messaging via API actually means
A mass message on Fansly is a single DM sent to many fans at once. You can send it from the Fansly dashboard one creator at a time — or you can call the Mass Messaging API and ship the same message across every creator on your roster simultaneously, with personalized content per fan.
The API exposes the full workflow:
- Send — fire a mass message to a fan segment with one call
- Queue — schedule messages for future delivery or A/B testing windows
- Stats — pull open rates, click rates, conversion data per blast
- Saved for Later — manage the draft queue programmatically (list, publish, delete, edit)
- Segmentation — filter recipients by subscription tier, spend tier, last activity, or custom fan lists
The same endpoints work whether you're sending to 100 fans on one creator or 100,000 fans across 20 creators.
How to send a Fansly mass message via API
The minimum viable mass message takes one API call:
POST /v1/mass-messages
{
"account_id": "creator-account-id",
"text": "Hey {{name}}, new content just dropped 🔥",
"recipients": "all_active_fans",
"media_ids": ["media-id-1"],
"price_cents": 999
}
The fields:
account_id— which connected creator the message is fromtext— the message body, with{{name}}and other template variablesrecipients—all_active_fans,all_expired_fans,all_fans, a custom list ID, or an explicit array of fan IDsmedia_ids— optional, attach photos or videos to the messageprice_cents— optional, makes the attached media pay-per-view (PPV)
The Fansly API queues the deliveries, handles rate limits, and surfaces real-time progress via webhook so you know when the send is complete.
For non-technical teams, the same operation is available as a Zapier instant trigger or a Make.com module — no code required after the initial setup.
Mass messaging use cases that pay back fastest
These are the campaign types agencies ship in their first week with the API:
PPV blasts → $1,000-$20,000 per campaign per creator
Schedule a PPV (pay-per-view) media blast on Fridays at 9pm in each creator's timezone. Personalize the opener per fan, attach the media, set a price. Watch revenue land in the tracking link dashboard.
Why it matters: PPV is the highest-margin monetization on Fansly. Manual PPV scheduling per creator burns hours every week. One workflow per creator + one cron trigger sends the same campaign across the roster automatically.
Welcome sequence → activate new subs in the first 48 hours
Trigger on subscription.created webhook, wait 1 hour, send a personalized welcome DM. Wait 24 hours, send a follow-up with a low-priced PPV. Wait 48 hours, send a free preview to drive the next purchase.
Why it matters: the first 48 hours of a Fansly subscription is when fans are most engaged. Agencies that automate welcome sequences see 3-5x higher first-week PPV conversion vs. agencies that wait for chatters to manually reach out.
Win-back on expired subs → recover 15-25% with one DM
Trigger on subscription.expired, wait 7 days, send a personalized DM with a discount code from the Promotions endpoint and a tracking link to measure conversion.
Why it matters: expired-sub winback is recurring revenue that most agencies leave on the table. A 20% recovery rate across 5,000 expired fans = 1,000 reactivated subs from one workflow.
Birthday & holiday outreach → loyalty without manual effort
Pull fan birthday data from the Fans endpoint, schedule a personalized birthday message with a special offer. Same pattern for Valentine's, Halloween, NSFW holidays, etc.
Why it matters: fans who receive birthday outreach are 2-3x more likely to renew at end of cycle. One workflow handles 5,000+ birthdays/year automatically.
Saved for Later → schedule a week of content in 30 minutes
Use the Saved for Later API to queue 7 days of mass messages in one sitting — Sunday night planning session for the whole week across every creator on your roster.
Why it matters: instead of chatters logging in daily across 20 accounts to send messages, ops schedules a week of campaigns in 30 minutes on Sunday. Everything runs automatically.
A/B test what actually converts
Send variant A to 50% of a fan segment, variant B to the other 50%. Compare conversion via tracking links. Promote the winner across the full segment.
Why it matters: "this template gets more replies" is anecdote until you measure. A/B testing turns chatter intuition into data — and reveals templates that work across creators vs templates that only work for one.
Tips before you scale mass messaging across your roster
- Personalize beyond
{{name}}. Pull spend tier, days-since-last-purchase, or last message topic into the template. Generic blasts get reported as spam; personalized blasts get replies. - Respect rate limits. Each Fansly account has a messaging cap. The API handles pacing automatically, but plan large campaigns for off-peak windows to avoid queue backups.
- Always include a tracking link. Without one, you cannot measure which campaign drove which revenue. Build attribution into every blast.
- Test segments before full sends. Run a campaign to a 100-fan slice first. If the open/reply rate is low, kill it before burning credits on 10,000 fans.
- Watch for fan complaints. Set up a webhook trigger on
message.receivedto flag fans who reply with negative sentiment. The Fans endpoint's restrict/block actions let you handle them programmatically.
Pricing for Fansly mass messaging
Each mass message campaign consumes credits. The cost scales with recipient count, personalization depth, and attached media.
Rough estimates per blast:
- 1,000 fans, plain text — ~30 credits
- 10,000 fans, personalized — ~150 credits
- 10,000 fans + PPV media — ~250 credits
Plans and credit allowances:
- Basic — $69/month: 20,000 credits, 1 account, Mass Messaging API included
- Pro — $299/month: 100,000 credits, 5 accounts, full webhook access
- Enterprise — 100+ accounts: dynamic pricing as low as $11.60 per account, custom credits
A single PPV blast that generates $5,000 typically costs under $5 in API credits. The ROI math is straightforward.

Frequently asked Fansly mass messaging questions
How many fans can I message in one Fansly mass message? There is no hard cap on the fan count per mass message. The Fansly API queues and rate-limits deliveries safely so you can target 10,000+ fans in a single blast without triggering account flags.
Can I personalize each Fansly mass message? Yes. Template variables let you insert fan name, last purchase amount, subscription tier, time since last message, and any custom data you store. Each fan receives a unique-feeling DM at scale.
Will the Fansly Mass Messaging API replace my chatters? No — it removes the boring half. Mass messages handle the repetitive blasts (PPV drops, welcome sequences, win-backs) so chatters spend their time on high-intent 1:1 conversations and PPV upsells where their judgment actually matters.
How much does one Fansly mass message campaign cost in credits? A mass message to 10,000 fans typically consumes 100-300 credits depending on personalization depth and media attachments. The Credits Calculator in the dashboard shows the exact cost before you hit send.
Can I A/B test Fansly mass messages? Yes. Send variant A to one fan segment, variant B to another, compare conversion via tracking links or webhook responses, then scale the winner. Most agencies run 2-3 active tests per creator at any given time.
