A questionnaire has little to do with sampling technique. Sampling technique is to do with who gets the questionnaire and that can be any sampling technique: the questionnaire can be sent to everyone (census), to a random sample, stratified random samples, to random samples in clusters, by quota or convenience. Or a pile of questionnaires can be left for respondents to pick up - self-selection.

Disadvantages of systematic sampling: © The process of selection can interact with a hidden periodic trait within the population. If the sampling technique coincides with the periodicity of the trait, the sampling technique will no longer be random and representativeness of the sample is compromised.
Two factors that affect the choice of a sampling technique are the population size and the level of accuracy required. For large populations, it may be more practical to use a random sampling technique, while for small populations, a convenience sampling technique may be sufficient. Additionally, if high accuracy is required, a stratified sampling technique may be more appropriate to ensure representation of all subgroups within the population.
So-called accidental sampling. Please see the link.
Sampling techniques can provide statistically reliable and valid survey results except haphazard sampling.
