FAQ - Automate your mailing campaigns
How many e-mails per sequence?
3 to 7, depending on the objective. Beyond that, marginal yield drops sharply. A good welcome sequence has 3 to 5 e-mails; an abandoned basket sequence, 2 to 3.
How often should the manual newsletter be sent?
1 to 2 per month for the majority of Belgian SMEs. In B2B, monthly is sufficient. In e-commerce, you can go up to 4 per month with fine-tuned segmentation.
Is mailing still effective in the face of social networking?
Yes, and by far it remains so. E-mail still delivers the best ROI of all digital channels, especially in B2B. It's also an asset you own - unlike your subscribers on social platforms.
How long does it take to see results?
First conversions within the first month. Full maturity of an automated strategy in 4 to 6 months after implementation and ongoing optimization.
