What reaches both
2 kinds of post reach both Instagram and Pinterest:
| You upload | On Instagram | On Pinterest |
|---|---|---|
| Social photo post — a photo with a caption | Posted as a photo on your Instagram feed. | Created as a Pin on your Pinterest board. |
| Product — a product with a photo and price | Promo photo posted to Instagram. | Created as a product Pin on Pinterest. |
What does not carry across
Worth knowing before you plan a batch — these are limits of the networks, not of the tool:
- Reel / Short video reaches Instagram but not Pinterest.
Limits worth knowing first
- Instagram: Publishing goes through a Facebook Page — an Instagram professional account has to be linked to one. Reels are not live until Instagram finishes transcoding, which can take several minutes.
- Pinterest: A Pin title is capped at 100 characters and the description at 500.
Connecting the two accounts
- Instagram connects with one click, through its own login screen.
- Pinterest connects with one click, through its own login screen.
Both connect once and stay connected; if a network expires its own token, the account is paused and you are emailed to reconnect it rather than left with posts silently failing.
How it works
- Connect Instagram and Pinterest in Integrations.
- Upload your photo or product once and pick both as targets.
- Let the AI write a caption per network, or write your own.
- Publish now, or schedule it. Each delivery is tracked separately.
Frequently asked questions
Can I post to Instagram and Pinterest at the same time?
Yes. social photo post and product posts reach both Instagram and Pinterest from a single upload — you choose both as targets and publish once.
Does the caption have to be identical on Instagram and Pinterest?
No. SOSPosting writes a separate, native caption for each network — the length, tone and hashtags that suit Instagram are not the ones that suit Pinterest. You can edit either before publishing, or write both yourself.
What can I not send to both?
A vertical video post reaches Instagram but not Pinterest. Those are limits of the networks themselves, not of the tool.
What happens if one of them fails?
Each network is delivered independently, so one failing does not block the other. A delivery that fails for good is refunded automatically — you are not charged tokens for a post that never went out.
