The review of SMS campaigns can take anywhere between a couple of minutes and a few hours. Unfortunately, to avoid spam, we need to review every SMS campaign. Also, any sent campaign is closely followed by a team member to ensure the best deliverability.
Rest assured that we will never send your campaign during night-time. Any time we moderate campaigns, we check your local timezone and avoid sending within the 10PM - 9AM timeframe. Any campaigns that were not accepted during the day, will be sent after 9AM your time the 2nd day.
The best suggestion for time sensitive campaigns is to schedule campaigns with 12 hours in advance via chat. Feel free to contact us to find the best sending for your SMS campaign.
